Synthesis of Electromagnetic Metasurfaces: Principles and Illustrations
Karim Achouri, Bakthiar Ali Khan, Shulabh Gupta +3
The paper presents partial overview of the mathematical synthesis and the physical realization of metasurfaces, and related illustrative examples. The synthesis consists in determi…
Metasurface Spatial Processor for Electromagnetic Remote Control
Karim Achouri, Guillaume Lavigne, Mohamed Ahmed Salem +1
We introduce the concept of metasurface spatial processor, whose transmission is remotely and coherently controlled by the superposition of an incident wave and a control wave thro…
Space-Time Cross-Mapping and Application to Wave Scattering
Mohamed A. Salem, Christophe Caloz
Causality creates an asymmetry between space and time, even though the wave equation treats them on equal footing. In this work, we leverage this asymmetry to construct a cross-map…
