Simultaneous Control of the Spatial and Temporal Spectra of Light with Space-Time Varying Metasurfaces
Nima Chamanara, Yousef Vahabzadeh, Christophe Caloz
This paper presents space-time varying (STV) metasurfaces for simultaneously controlling the spatial and temporal spectra of electromagnetic waves. These metasurfaces transform inc…
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…
Mathematical Synthesis and Analysis of Nonlinear Metasurfaces
Karim Achouri, Yousef Vahabzadeh, Christophe Caloz
We propose a discussion on the synthesis and scattering analysis of nonlinear metasurfaces. For simplicity, we investigate the case of a second-order nonlinear isotropic metasurfac…
Spacetime Processing Metasurfaces: GSTC Synthesis and Prospective Applications
Nima Chamanara, Yousef Vahabzadeh, Karim Achouri +1
The paper presents the general concept of spacetime processing metasurfaces, synthesized by generalized sheet transition conditions (GSTCs). It is shown that such metasurfaces can…
