Metasurface Magnetless Specular Isolator
Guillaume Lavigne, Toshiro Kodera, Christophe Caloz
We present a (nongyrotropic) metasurface magnetless specular isolator. This device reflects as a mirror a wave incident under a specified angle in one direction and absorbs it in t…
Magnetless Reflective Gyrotropic Spatial Isolator Metasurface
Guillaume Lavigne, Christophe Caloz
We present the concept of a magnetless Reflective Gyrotropic Spatial Isolator (RGSI) metasurface. This is a birefringent metasurface that reflects vertically polarized incident wav…
Generalized Brewster Effect using Bianisotropic Metasurfaces
Guillaume Lavigne, Christophe Caloz
We show that a properly designed bianisotropic metasurface placed at the interface between two arbitrary different media, or coating a dielectric medium exposed to the air, provide…
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…
Comparison of Tensor Boundary Conditions (TBCs) with Generalized Sheet Transition Conditions (GSTCs)
Mojtaba Dehmollaian, Guillaume Lavigne, Christophe Caloz
This paper compares Tensor Boundary Conditions (TBCs), which were introduced to model multilayered dielectric structures, with Generalized Sheet Transition Conditions (GSTCs), whic…
