Generalized Optical Signal Processing Based on Multi-Operator Metasurfaces Synthesized by Susceptibility Tensors
Ali Momeni, Hamid Rajabalipanah, Ali Abdolali +1
This paper theoretically proposes a multichannel functional metasurface computer characterized by Generalized Sheet Transition Conditions (GSTCs) and surface susceptibility tensors…
Influence of Reciprocity, Symmetry and Normal Polarizations on the Angular Scattering Properties of Bianisotropic Metasurfaces
Karim Achouri, Olivier J. F. Martin
This paper aims at studying the angular scattering properties of bianisotropic metasurfaces and at clarifying the different roles played by tangential and normal polarization densi…
Surface-Wave Dispersion Retrieval Method and Synthesis Technique for Bianisotropic Metasurfaces
Karim Achouri, Olivier J. F. Martin
We propose a surface-wave dispersion retrieval method and synthesis technique that applies to bianisotropic metasurfaces that are embedded in symmetric or asymmetric environments.…
What is Nonreciprocity?
Christophe Caloz, Andrea Alù, Sergei Tretyakov +3
This paper aims at providing a global perspective on electromagnetic nonreciprocity and clarifying confusions that arose in the recent developments of the field. It provides a gene…
What is Nonreciprocity? Part II
Christophe Caloz, Andrea Alù, Sergei Tretyakov +3
This paper is the second part of a two-part paper on \emph{Electromagnetic (EM) Nonreciprocity (NR)}. Part~I has defined NR, pointed out that linear NR is a stronger form of NR tha…
Homogenization and Scattering Analysis of Second-Harmonic Generation in Nonlinear Metasurfaces
Karim Achouri, Gabriel D. Bernasconi, Jérémy Butet +1
We propose an extensive discussion on the homogenization and scattering analysis of second-order nonlinear metasurfaces. Our developments are based on the generalized sheet transit…
Study of the Angular Spectrum of a Bianisotropic Refractive Metasurface at a Dielectric Interface
Guillaume Lavigne, Karim Achouri, Christophe Caloz
We present an initial study of the angular spectrum of a bianisotropic refractive metasurface at an interface between two dielectric media. In this study, we report on the existenc…
