The course in divided in two main parts. In the first part an introduction to artificial surfaces and how to analyze and design them for different applications (stop band, equivalent refraction index, etc.) will be presented. In particular, two main scenarios will be considered with the corresponding applications, metasurfaces embedded in parallel plate waveguides and metasurfaces (MTS)in open environements. The second part of the course will be devoted to gap waveguide technology which is an example of application of these meta-surfaces. Here, the fundamentals of the technology and its application to the design of antennas and components will be described. Along the course, the students will do some activities with laptops. The contents of the course can be summarized as: • Introduction to characterization of periodic structures (MTS) (1 hour) • MTS embedded in PPW (2 hours+ 1 hour lab.): – Calculation of Equivalent Refractive Index: application in Meta-lenses – EBG Designs: application in gap waveguide and packaging • MTS in open environments (2 hours+ 1 hour lab.): – Applications when combined with antennas – Applications as RIS or to reduce RCS ( • Antenna Design in Gap Waveguide Technology (2 hours+ 1 hour lab.)

The course is divided into two main parts. The first part introduces artificial surfaces, focusing on their analysis and design for various applications, such as stop bands and equivalent refractive index. It covers two main scenarios: metasurfaces in parallel plate waveguides and metasurfaces in open environments. The second part explores gap waveguide technology, a practical application of metasurfaces, detailing its fundamentals and use in antenna and component design. Guest lecturer: - Eva Rajo-Iglesias (Full Professor University Carlos III of Madrid): Eva Rajo Iglesias (Monforte de Lemos, 1972) is a Full Professor at the Dpt. of Signal Theory and Communications at the Carlos III University of Madrid since 2018. She has been an Affiliated Professor at the Antenna Group at Chalmers University (Sweden) between 2009 and 2016. She is Head of the Radio Technologies and Applications research group of the UC3M (https://gea.webs.tsc.uc3m.es/). Her research activity is related to printed antennas, artificial surfaces and periodic structures, higher symmetries, gap waveguide technology, and MIMO systems. In the topic of gap waveguide technology, she has published 35 journal articles, a book chapter, two patents and she has organized special sessions in the main international conferences of antennas. She has also given short courses about this topic in conferences like EuCAP or IEEE APS and in the European School of Antennas. She has been plenary speaker in the conference in EuCAP 2017 with the talk: “Antenna designs based on Gap Waveguide Technology". More recently she gave an Opening talk in the European Microwave Week 2021 in the EuRAD conference about the same topic and a keynote talk in ISAP 2022.
