Magnetic pulse welding (MPW) is a collision welding process, which uses a high velocity impact to join the two metals. This method allows for the joining of similar and dissimilar metals without the input of external heat and without any critical formation of their intermetallic phases. Sheets, profiles, and tubes can be processed. During the MPW process the parts being welded are positioned inside a tool coil. During the fast discharge of the capacitor banks via the coil, a magnetic field is generated around the coil, which leads to eddy currents in the electrically conductive flyer part positioned in close vicinity to the coil. The eddy currents induced in the flyer create an opposite magnetic field and a repulsive Lorentz force. This force causes the flyer to quickly accelerate plastically and to impact with the inner parent at an extremely high velocity resulting in a metallic bond. One of the simplest ways of obtaining information about the electromagnetic processes which take place during MPW is to measure the waveform of the magnetic field in the gap between the coil or field shaper and the flyer. In this work, it was investigated how fast, small size CMR-B-scalar sensors could be used for the measurements of the magnetic field magnitudes in the gap between the flyer and the field shaper during MPW and how they can provide quick, non-destructive evaluations of the weld quality. 
 and  “Magnetic Field Dynamics During Magnetic Pulse Forming“

Magnetic Pulse Forming (MPF) is an innovative and environmentally friendly method of forming metal workpieces by the controlled application of magnetic forces. To ensure the quality and accuracy of the MPF process, it is important to monitor the dynamics of the applied magnetic field magnitude in real time. Analysis of the magnetic field dynamics can provide information about the material forming process. This paper discusses the possibility of using manganite oxide-based sensors as an effective control method in the MPF process. Sensors based on manganite oxides (e.g., La1-xSrxMnO3) have a colossal magnetoresistance, their compact size allows to be placed in the gap between the workpiece and the coil, and they are ideal candidates for monitoring the dynamics of magnetic fields with a magnitude of more than 1 Tesla and a duration of tens of microseconds. Numerical modeling of the workpiece deformation process and the dynamics of the magnetic field in the gap between the workpiece and the coil are discussed. 
14:15 – 14:50 “Field hetrogenity estimatiom for sixth-order symmetrical current loop systems“, Romans Kusnis, Janis Semenako, Anna Litvinenko, Raivis, Deksnis – Institute of Microwave Engineering and Electronics Riga Technical University Riga, Latvia 
The magnetic field of symmetrical three-coil DC current loop systems is investigated. All coils are arranged in parallel with their centers aligned along the same axis. The obtained results are applicable to very low-frequency current fields. Assuming negligible cross-sections for the coils, we derive a universal solution for the magnetic field expressed in terms of elliptic integrals, with the coil radii and distances between them serving as system parameters. The commonly used design technique for coil systems that aims to provide maximally homogeneous fields relies on expanding the field generated by the coil system into a Taylor series centered at the origin. In our investigation, the coil system is oriented so that the axis connecting the coil centers corresponds to the z-axis, with the coordinate z=0 representing the center of symmetry. This orientation ensures homogeneity along the z-axis, which, in turn, guarantees a sufficient level of field uniformity in other directions around the origin. 
Analytical calculations reveal that the axial component of the magnetic field along the z-axis is an odd function of z. Consequently, the Taylor series exclusively contains even-order terms. To enhance field homogeneity, several lower-order even derivatives within the series can be set to zero. For a tri-coil system, physically realizable solutions are obtained by setting the 2nd and 4th-order derivatives equal to zero, resulting in a sixth-order tri-coil system. Importantly, there exist infinitely many such solutions achieved by varying the radius of the middle coil and the distance of the outer coils from the center. Notably, coil systems where the radius of the middle coil falls within 0.5 to 1.5 times the radius of the outer coils are particularly interesting for practical applications. 
The primary focus of this research is to determine which of these coil systems offers the best field uniformity (heterogeneity). To address this, we investigate how to evaluate and compare the heterogeneity of such coil systems, despite their differing geometric dimensions and occupied volumes. Furthermore, we explore the extent to which the non-zero terms in the Taylor series impact field homogeneity. The research findings highlight the absence of universal solutions and emphasize the need for additional criteria tailored to specific applications, such as constraints on maximum radial system size or dimensions in the longitudinal direction. 
14.50 – 15:25 “Overview of in-vehicle microwave sensors” , Dr. Eldar Sabanovic 
Senior Research Fellow at Transport and Logistics Competence Centre, Faculty of Transport Engineering, Associate Professor at Department of Electronic Systems, Faculty of Electronics

15:25–  15:45 Coffee break 
15:45 – 16:20 ” Advanced techniques for Wireless power transfer“, Janis Eidaks1 , Romans Kusnins 1, Ruslans Babajans 1 , Darja Cirjulina 1, 2 , Anna Litvinenko 1,2

The growing number of low-power wireless devices and sensors led to the integration of the Internet of Things (IoT) and Wireless Sensor Networks (WSNs) in various branches of industry, agriculture, medicine, etc. With such wide application, the powering of the autonomous sensor nodes (SNs) poses a challenge since batteries are the most common power source of the SNs. The growing interest in overcoming this challenge was directed toward developing far field wireless power transfer (WPT). While the given powering technique is feasible, WPT performance enhancement is the main challenge. The device-level improvements focus on enhancing the performance of the WPT nodes. This includes improving the performance of the RF-DC converters, energy storage solutions, and the design of power-carrying signal waveforms. The network-level improvements are focused on incorporating and combining new technologies, such as multi-hop transfer and beamforming, to increase the performance of WPT on a network scale. The current project aims to investigate and experimentally study several innovative techniques of wireless power transfer: multi-hop energy transfer, passive beamforming using intelligent reflecting surfaces (IRSs), and application of RF powering signals adapted to the transmission channel. The research also studies the combinations of the techniques for more efficient WPT. 
16:20 – 16:55 “Open structures in electromagnetics: scientific heritage of Victor P. Shestopalov“, Yury Shestopalov – Faculty of Engineering and Sustainable Development, University of Gävle, Sweden. 
 We briefly summarize the milestones describing comprehensive scientific acitivities and results achieved by Victor P. Shestopalov and his disciples in the fields specifically connected with applications of the nonselfadjoint operator spectral theory in electromagnetics of open structures. We emphasize that his achievements paved the way to creating the modern level of the mathematical theory of wave propagation and diffraction and resulted in constructing efficient solution techniques and discovery of various phenomena and effects. 
 
16:55 – 17:30 “Mobile FMCW Radar Technology in cm Range” Dr. Borisas Levitas, Michael Drozdov, Matvej Khazarov – Geozondas LTD, Lithuania. 
 An overview of frequency domain Software Defined Radars (SDR) was completed. The Frequency Modulated Continuous Wave (FMCW) radar with multiple receiving antennas after the initial processing (some form of Fourier transforms) creates a Range-Azimuth-Doppler 3D data array on each frame. The schemes and signal processing algorithms of SDR through wall radar developing in frame of project FRED were described.   A printed Aperture Stacked Patch Antenna were calculated and simulated. 4 antenna transmitting array and 8 antenna receiving array form a 32 elements virtual array. A decade convolutional neural networks (CNN) is used to improve probability and accuracy of though wall live being target detection and localization with a minimum number of false alarms. Our goal with the CNN was to improve the performance of the proprietary FMCW radar, find a data representation that allows to conveniently store the radar data but also have an efficient data pipeline during the training phase and find a set of data augmentation strategies to avoid overfitting to the training set. 
17:30 – 18:00 “Event timer-based PPM transceiver design and implementation“, Arturs Aboltins1, Tatjana Solovjova1, Viktors Kurtenoks2   
1 Institute of Microwave Engineering and Electronics Riga Technical University Riga, Latvia 
2 Eventech Ltd, Riga, Latvia 
The employment of event timers for the demodulation of pulse position modulation (PPM) signals allows the building of data communication systems with unprecedented energy efficiency and competitive transmission speeds. PPM modulation techniques can be employed for space communications, sensor networks, high-accuracy integrated sensing and communications.
This presentation is devoted to the PPM transceiver design capable of transmitting data with a data transfer speed of up to 160 Mbit/s and energy efficiency of less than 5 pJ/bit. The transceiver employs Eventech ESTT-01 event-timer to demodulate the signal, whereas the modulation uses high-speed digital delay lines. In the first part, design decisions, main challenges and prospects of high-speed communication using PPM. are addressed. The second part analyzes the impact of optical and microwave links on the transmitted waveform, and electro-optical solutions for transmitter/receiver front-ends are proposed. It will be shown how a pulse expander could be implemented either in the optical or in the electrical domain of the PPM communication link to satisfy the requirements of the event timer for input signal duration.

For example, they are being considered for antenna solutions in 5G/6G, satellite communications in Low-Earth Orbit constellations and automotive radars. However, their simulation and optimization are time-consuming due to their large dimensions in terms of wavelength. In this presentation, Prof. Quevedo-Teruel will explain the theory of ray-tracing, its features, and he will demonstrate its operation with some practical examples. 

9:45 – 10:30 Prof. Mike Hinchey (UK) –  Is There Anything That Isn’t Software? (https://events.vtools.ieee.org/m/373035) 

In this rapidly changing world, evolving technologies such as Artificial Intelligence, Robotics, Machine Learning, Cloud Computing, Big Data, the Internet of Things, and Mobile Computing are combining to disrupt traditional models and radically change how we live, work, and interact. More importantly, these technologies change the way we live and do business: the world’s largest bookstore is a Cloud Computing provider, and the largest fleet of cars in the world is operated by an app provider. Areas such as healthcare have been transformed dramatically, with better analysis, imaging, detection, diagnosis, treatment, robot-assisted surgery, and even significant advances in sharing health records. We eagerly await the day when cars, buses, trucks, and railways are self-driven, and Industry 4.0 is already upon us, and of course we claim the use of AI in just about everything. All of these advances are entirely dependent on software. We ask the question: is there anything that isn’t software?

Abstract: In this rapidly changing world, evolving technologies such as Artificial Intelligence, Robotics, Machine Learning, Cloud Computing, Big Data, the Internet of Things, and Mobile Computing are combining to disrupt traditional models and radically change how we live, work, and interact. More importantly, these technologies change the way we live and do business: the world’s largest bookstore is a Cloud Computing provider, and the largest fleet of cars in the world is operated by an app provider. Areas such as healthcare have been transformed dramatically, with better analysis, imaging, detection, diagnosis, treatment, robot-assisted surgery, and even significant advances in sharing health records. We eagerly await the day when cars, buses, trucks, and railways are self-driven, and Industry 4.0 is already upon us, and of course we claim the use of AI in just about everything. All of these advances are entirely dependent on software. We ask the question: is there anything that isn’t software?
