Dr. Quevedo-Teruel

Welcome to my personal webpage

I am an Associate Professor in the School of Electrical Engineering and Computer Science (EECS) at KTH Royal Institute of Technology.
Director of the Master Programme in Electromagnetics, Fusion and Space Engineering at KTH.

Narrative biography:

Oscar Quevedo-Teruel received his degree in Telecommunication Engineering 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 PhD from Carlos III University of Madrid in 2010 and was then invited as a postdoctoral researcher at 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 School of Electrical Engineering and Computer Science (EECS)/Electromagnetic Engineering (ETK) 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 is an Associate Editor of the IEEE Transactions on Antennas and Propagation since 2018, and he is the delegate of EurAAP for Sweden, Norway and Iceland for the period 2018-2020. He is a distinguished lecturer of the IEEE Antennas and Propagation Society for the period 2019-2021.

He was the recipient of the Award of Excellence in 2010 from Carlos III University of Madrid. In 2010, he also received the National Award of Arquimedes for the best supervisory of M. Sc. Theses in Engineering and Architecture throughout Spain. Recently, in 2012, he received the prestigious Raj Mittra Junior Travel Grant.

He has made a significant scientific contribution to higher symmetries (glide and twist), transformation optics, lens antennas, metasurfaces, leaky wave antennas, metamaterials, multi-mode microstrip patch antennas and high impedance surfaces. He is the co-author of more than 60 papers in international journals, more than 120 at international conferences and has received approval on 2 patents.

Topics of Research

Higher symmetries structures:

Periodic structures possess twist symmetry when their lattice is created by a translation and an angular rotation. If the angular translation is 2-fold, the angular movement becomes a mirroring, and the higher symmetry is named glide. Both glide and twist symmetries are higher-symmetry periodic structures.

Higher symmetries were intensively studied in the ‘60s and ‘70s, especially for the case of propagation in 1D periodicities, which were employed to produce leaky wave antennas.

Recently, the study of higher symmetries is again an active research topic in the fields of microwave technology, antennas and metamaterials.

Transformation Optics:

This is a technique that defines the exact modification of magnetic and dielectric constants required, so that the electromagnetic behaviour remains invariant after a transformation to a new coordinate system.

This technique can be used to design a number of electromagnetic devices. For instance, it can be applied to produce efficient lens antennas.

Metasurfaces:

Metasurfaces are extremely thin layers of sub-wavelength unit cells that can be employed for directing or preventing the propagation of electromagnetic waves.

The concept of metasurfaces can be applied to waves from radio-frequencies to optics, including microwaves and TeraHertz (THz) regimes.

Their applications are numerous, and may be used to improve the performance of already known devices such as antennas, fibre optics, circuits, radio-telescopes and satellites.
