Course content
The course will deal with modelling, design and applications of metamaterials defined by various types of symmetries for their in antennas. Several modelling methods will be presented, as well as a large spectrum of applications to millimeter-wave antennas such as lens antennas, integrated beamformers, leaky waves, metasurface antennas. Tutorials on Ansys HFSS will allow to simulate and design a glide-symmetric metamaterial for application to a lens antenna.
The program of the school can be found here.
Description of the course
The course will start from a presentation of basic properties of periodic structures and glide- and twist-symmetric metamaterials and metasurfaces, given by Prof. Guido VALERIO (Sorbonne University, France). Methods for the analysis of these structures will be presented by Prof. Francisco MESA (University of Seville, Spain) and Prof. Zvonimir SIPUS (University of Zagreb, Croatia): mode matching, coupled wave analysis, multimodal transmission matrix method, circuit models.
Applications to lens antennas for directional radiation at millimeter waves and beyond will be presented by Prof. Oscar QUEVEDO-TERUEL (Royal Institute of Stockholm, Sweden): wideband flat lenses, compressed lenses, polarizers, prisms, leaky waves...
Spatio-temporal symmetries such as PTD symmetries and the role of complmentarity and symmetries on metasurface antennas will be presented by Prof. Enrica MARTINI (University of Siena, Italy).
A full course on the role of symmetry and topology in metamaterials design, degeneracies and topological protected states will be given by Dr. Simon HORSLEY (University of Exeter, UK). These lectures are suitable for students who do not necessarily have experience on the topic.
Several guided-wave applications (EBG for gap waveguides, flanges, filters, matching layers, beamforming networks and leaky waves) will be presented by Prof. Eva RAJO-IGLESIAS (University Carlos III of Madrid, Spain).
Applications of metamaterials for modern communication systems will be given by Prof. Astrid ALGABA-BRAZALES (Polythecnic University of Cartagena, Spain).
Three tutorials on the modeling and design of higher-symmetric metamaterials with Ansys HFSS will be also offered (students are expected to have a laptop where they will be able to run the software).
A final test is planned on Thursday afternoon to obtain a certificate of completion and the credits related to the school.
