Nonreciprocal Phase Gradient Metasurface: Principle and Transistor Implementation
Guillaume Lavigne, Christophe Caloz
We introduce the concept of nonreciprocal nongyrotropic phase gradient metasurfaces. Such metasurfaces are based on bianisotropic phase shifting unit cells, with the required nonre…
Angle-Independent Nongyrotropic Metasurfaces
Guillaume Lavigne, Christophe Caloz
We derive a general condition for angle-independent bianisotropic nongyrotropic metasurfaces and present two applications corresponding to particular cases: an angle-independent ab…
Transmissive Suppressed-Order Diffraction Grating (SODG)
Ashutosh Patri, Guillaume Lavigne, Christophe Caloz
We present a novel type of Suppressed-Order Diffraction Grating(SODG). An SODG is a diffraction grating whose diffraction orders have all been suppressed except one that is selecte…
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…
