Quadrupolar susceptibility modeling of substrated metasurfaces with application to the generalized Brewster effect
Ville Tiukuvaara, Olivier J. F. Martin, Karim Achouri
We derive generalized sheet transition conditions (GSTCs) including dipoles and quadrupoles, using generalized functions (distributions). This derivation verifies that the GSTCs ar…
Spatial Symmetries in Multipolar Metasurfaces: From Asymmetric Angular Transmittance to Multipolar Extrinsic Chirality
Karim Achouri, Ville Tiukuvaara, Olivier J. F. Martin
We propose a framework that connects the spatial symmetries of a metasurface to its material parameter tensors and its scattering matrix. This provides a simple yet effective way t…
Multipolar Modeling of Spatially Dispersive Metasurfaces
Karim Achouri, Olivier J. F. Martin
There is today a growing need to accurately model the angular scattering response of metasurfaces for optical analog processing applications. However, the current metasurface model…
Floquet Analysis of Space-Time Modulated Huygens' Metasurfaces with Lorentz Dispersion
Ville Tiukuvaara, Tom J. Smy, Shulabh Gupta
A rigorous semi-analytical Floquet analysis is proposed for a zero-thickness space-time modulated Huygens' metasurface to model and determine the strengths of the new harmonic comp…
