Glide symmetries: a new degree of freedom for the design of periodic structures
Glide symmetries were employed for electromagnetic purposes during the 60s and 70s. Those works were focused on one-dimensional structures with potential application in low-dispersive leaky wave antennas. However, the development of planar/printed technologies in the 80s and 90s associated to their low-cost for low-frequency applications, the studies of glide symmetries stopped.
In the beginning of the 21st century, with arrival of metamaterials, there was a significant development of the understanding of periodic structures, and new methods of analysis were introduced. This theoretical development, together with the interest of industry in mm-waves, particularly for communications systems such as 5G/6G, created an opportunity to explore the possibilities of glide symmetries, especially in two-dimensional configurations.
Glide-symmetric structures has recently attracted the attention of researchers due to their attractive properties for practical applications. Among their interesting properties are low-dispersive responses in fully metallic structures such as parallel plate or co-planar waveguides (CPW), bandgaps associated to the symmetries and large electromagnetic bandgaps (EBGs).
In this talk, Dr. Quevedo-Teruel will describe the most significant works in glide symmetries, including their application for the design of gap-waveguide technology and planar lens antennas with steerable angles of radiation.

Biography:
Oscar Quevedo-Teruel is a Senior Member of the IEEE. He 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 Autonoma de Madrid as a research fellow and went on to continue his postdoctoral research at Queen Mary University of London from 2011-2013.
In 2014, he joined the Division for Electromagnetic Engineering in the School of Electrical Engineering and Computer Science at KTH Royal Institute of Technology in Stockholm, Sweden where he is a Full Professor, the Responsible for the Antenna Laboratory and Director of the Master Programme in Electromagnetics Fusion and Space Engineering. He has been an Associate Editor of the IEEE Transactions on Antennas and Propagation since 2018-2022 and Track Editor since 2022. He is a member of the Editoral Board of Nature Scientific Reports since 2021, and the founder and editor-in-chief of the EurAAP journal Reviews of Electromagnetics since 2020. He was the EurAAP delegate for Sweden, Norway, and Iceland from 2018-2020, and he has been a member of the EurAAP Board of Directors since January 2021. Since January 2022, he is the vice-chair of EurAAP. He is a distinguished lecturer of the IEEE Antennas and Propagation Society for the period of 2019-2022, and Chair of the IEEE Antennas and Propagation Society’s Educational Initiatives Programme since 2020.
He has made scientific contributions to higher symmetries, transformation optics, lens antennas, metasurfaces, leaky wave antennas and high impedance surfaces. He is the co-author of 120 papers in international journals and 200 at international conferences.
