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, 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.

He received his Telecommunication Engineering Degree from Carlos III University of Madrid, Spain in 2005, part of which was done at Chalmers University of Technology in Gothenburg, Sweden. He obtained his Ph.D. from Carlos III University of Madrid in 2010 and was then invited as a postdoctoral researcher to the University of Delft (The Netherlands). From 2010-2011, Dr. Quevedo-Teruel 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 an Associate Professor 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 and is the founder and editor-in-chief of the EurAAP journal Reviews of Electromagnetics. He was the EurAAP delegate for Sweden, Norway, and Iceland from 2018-2020 and he is now a member of the EurAAP Board of Directors. He is a distinguished lecturer of the IEEE Antennas and Propagation Society for the period of 2019-2022, and Chair of the IEEE APS 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 95 journal papers and 150 at international conferences.
