Design, Concepts and Applications of Electromagnetic Metasurfaces
Karim Achouri, Christophe Caloz
The paper overviews our recent work on the synthesis of metasurfaces and related concepts and applications. The synthesis is based on generalized sheet transition conditions (GSTCs…
Inverse Prism based on Temporal Discontinuity and Spatial Dispersion
Alireza Akbarzadeh, Nima Chamanara, Christophe Caloz
We introduce the concept of the inverse prism as the dual of the conventional prism and deduce from this duality an implementation of it based on temporal discontinuity and spatial…
Computational Analysis of Metasurfaces
Yousef Vahabzadeh, Nima Chamanara, Karim Achouri +1
Metasurfaces represent one of the most vibrant fields of modern science and technology. A metasurface is a complex electromagnetic structure, that is typically deeply subwavelength…
Flexible-Resolution, Arbitrary-Input and Tunable Rotman Lens Spectrum Decomposer (RL-SD)
Xiaoyi Wang, Alireza Akbarzadeh, Lianfeng Zou +1
We present an enhanced design -- in terms of resolution flexibility, input port position arbitrariness and frequency-range tunability -- of the planar Rotman lens spectrum decompos…
Metasurface Solar Sail for flexible Radiation Pressure Control
Karim Achouri, Christophe Caloz
We propose to use metasurfaces as a mean of controlling radiation pressure for increasing the range of motions of spacecraft solar sails. Specifically, we present a theoretical stu…
New Electromagnetic Modes in Space-Time Modulated Dispersion-Engineered Media
Nima Chamanara, Zoé-Lise Deck-Léger, Christophe Caloz +1
We report on new electromagnetic modes in space-time modulated dispersion-engineered media. These modes exhibit unusual dispersion relation, field profile and scattering properties…
