Refracting Metasurfaces without Spurious Diffraction
Guillaume Lavigne, Karim Achouri, Viktar Asadchy +2
Refraction represents one of the most fundamental operations that may be performed by a metasurface. However, simple phasegradient metasurface designs suffer from restricted angula…
Perfectly Refractive Metasurface using Bianisotropy
Guillaume Lavigne, Karim Achouri, Christophe Caloz +2
A passive and reciprocal perfectly refractive metasurface is designed using a general susceptiblity synthesis method. The metasurface uses weak spatial dispersion in the form of bi…
Controllable Angular Scattering with a Bianisotropic Metasurface
Karim Achouri, Christophe Caloz
We propose the concept of a bianisotropic metasurface with controllable angular scattering. We illustrate this concept with the synthesis and the analysis of a metasurface exhibiti…
