Compact grating coupler using asymmetric waveguide scatterers
Ashutosh Patri, Xiao Jia, Muhammad Mohsin +2
We demonstrate a novel grating coupler design based on double asymmetric and vertically oriented waveguide scatterers to efficiently couple normally incident light to a fundamental…
Linear Pulse Compansion using Co-propagating Space-Time Modulation
Nima Chamanara, Christophe Caloz
This paper presents a pulse compansion, i.e. compression or expansion, technique based on co-propagating space-time modulation. An engineered asymmetric space-time modulated medium…
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…
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…
Extending the Brewster Effect to Arbitrary Angle and Polarization using Bianisotropic Metasurfaces
Guillaume Lavigne, Christophe Caloz
A bianisotropic metasurface design is proposed for extending the Brewster effect to arbitrary angles and polarizations. The metasurface is synthesized using the surface susceptibil…
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…
