摘要

In this paper, a low-cost, simple, and reliable bi-static radar cross-section (RCS) measurement method by using a historic Marconi set-up is presented. It uses a transmitting (Tx) antenna (located at a constant position, at a reference angle of θ=0∘θ=0∘) and a moving receiver (Rx) antenna. A time gating method is used to extract the information from the reflection in the time domain; applying time filter allows removing the antenna side-lobe effects and other ambient noises. In this method, the Rx antenna (on the movable arm) is used to measure the reflected field in the angular range from 1∘1∘ to 90∘90∘ from the structure (printed circuit board, PCB) and the reference configuration represented by a ground (GND) plane of the same dimension. The time gating method is then applied to each pair of PCB/GND measurements to extract the bi-static RCS pattern of the structure at a given frequency. Here, a comparison of measurement results is carried out at 18 and 32 GHz with simulation ones indicating successful performance of the proposed method. It can be used as a low-cost, reliable, and available option in future measurement and scientificresearch.

Ladislau Matekovits received the degree in electronic engineering from Institutul Politehnic din Bucureşti, Bucureşti, Romania, and the Ph.D. degree (Dottorato di Ricerca) in electronic engineering from Politecnico di Torino, Torino, Italy, in 1992 and 1995, respectively.

Since 1995, he has been with the Department of Electronics and Telecommunications, Politecnico di Torino, first with a post-doctoral fellowship, then as a Research Assistant. He joined the same department as an Assistant Professor in 2002 and was appointed as a Senior Assistant Professor in 2005 and as an Associate Professor in 2014. In February 2017, he received the Full Professor qualification (Italy). In late 2005, he was a Visiting Scientist with the Antennas and Scattering Department, FGAN-FHR (now Fraunhofer Institute), Wachtberg, Germany. From July 1, 2009, for two years, he has been a Marie Curie Fellow with Macquarie University, Sydney, NSW, Australia, where, in 2013, he also held a Visiting Academic position and, in 2014, was appointed as an Honorary Fellow. Since 2020, he has been an Honorary Professor with the Polytechnic University of Timisoara, Romania and an Associate of the Italian National Research Council. He has been appointed as a Member of the National Council for the Attestation of University Degrees, Diplomas, and Certificates (CNATDCU), Romania, for the term 2020–2024.

His main research activities concern numerical analysis of printed antennas and, in particular, development of new, numerically efficient full-wave techniques to analyze large arrays, and active and passive metamaterials for cloaking applications. Material parameter retrieval of these structures by inverse methods and different optimization techniques has also been considered. In the last years, bio-electromagnetic aspects have also been contemplated, as, for example, design of implantable antennas or development of nano-antennas, for example, for drug delivery applications.

He has published 375+ papers, including 100+ journal contributions, and delivered seminars on these topics all around the world: Europe, USA (AFRL/MIT-Boston), Australia, China, Russia, etc. Prof. Matekovits has been invited to serve as Research Grant Assessor for government funding calls (Romania, Italy, Croatia, and Kazakhstan) and as International Expert in Ph.D. thesis evaluation by several universities from Australia, India, Pakistan, Spain, etc.

Dr. Matekovits has been a recipient of various awards in international conferences, including the 1998 URSI Young Scientist Award (Thessaloniki, Greece), the Barzilai Award 1998 (Young Scientist Award, granted every two years by the Italian National Electromagnetic Group), and the Best AP2000 Oral Paper on Antennas, ESA-EUREL Millennium Conference on Antennas and Propagation (Davos, Switzerland). He is a recipient of the Motohisa Kanda Award 2018, for the most cited paper of the IEEE Transactions on Electromagnetic Compatibility in the past five years, and, more recently, he has been awarded with the 2019 American Romanian Academy of Arts and Sciences (ARA) Medal of Excellence in Science and by the Ad Astra Award 2020, Senior Researcher, for excellence in research.

He has been an Assistant Chairman and Publication Chairman of the European Microwave Week 2002 (Milan, Italy) and General Chair of the 11th International Conference on Body Area Networks (BodyNets) 2016. Since 2010, he has been a member of the organizing committee of the International Conference on Electromagnetics in Advanced Applications (ICEAA), and he is a member of the technical program committees of several conferences. He serves as an Associated Editor for the IEEE Access, IEEE Antennas and Wireless Propagation Letters, and IET Microwaves, Antennas & Propagation and as a Reviewer for differentjournals.
