Oscar Quevedo-Teruel of KTH Royal Institute of Technology, Stockholm, Sweden

In recent years, we have become familiar with using commercial software to design our antennas and microwave devices. This is very common because high-performance desktop computers are easy to find at affordable prices in our daily lives. The use of general-purpose commercial software is widespread because it enables the simulation of arbitrary configurations. However, many of us have experienced, given the ease of using commercial software, the difficulty of simulating electrically large electromagnetic devices, which can take days or, in some cases, cannot be completed at all. While it is true that we now have very powerful simulation tools, by making a few simple assumptions, we can significantly reduce computational time without sacrificing accuracy [1]. In this talk, I will introduce a simple ray-tracing technique that can be used, in combination with physical optics, to calculate the radiation pattern, directivity, gain, mutual coupling, and even the early-time response of antennas in complex configurations [2-4]. The results are not only faster than those produced by conventional commercial software, but also more accurate, as they avoid many of the numerical errors that typically arise when computing electrically large structures.

Biography:

Oscar Quevedo-Teruel received his Telecommunication Engineering and Ph.D. degrees from Carlos III University of Madrid, Spain, in 2005 and 2010. From 2010-2011, he joined the Department of Theoretical Physics of Condensed Matter at Universidad Autónoma de Madrid as a research fellow and continued his postdoctoral research at Queen Mary University of London from 2011-2013. In 2014, he joined KTH Royal Institute of Technology in Stockholm, Sweden, where he is a Professor in the Division of Electromagnetic Engineering and Fusion Science and Director of the Master's Program in Electromagnetic Fusion and Space Engineering. He served as an Associate Editor of the IEEE Transactions on Antennas and Propagation from 2018 to 2022 and as a Track Editor since 2022. He has been a member of the European Association on Antennas and Propagation (EurAAP) Board of Directors since January 2021. Since January 2022, he has been the vice-chair of EurAAP. He was a distinguished lecturer for the IEEE Antennas and Propagation Society during 2019-2021. He is an IEEE Fellow for his contributions to glide-symmetry-based metasurfaces and lens antennas. He has made scientific contributions to periodic structures, higher symmetries, transformation optics, lens antennas, physical optics, and high-impedance surfaces. He is the co-author of more than 150 papers in international journals and 300 papers at international conferences.
