Pole-Expansion of the T-Matrix Based on a Matrix-Valued AAA-Algorithm
Jan David Fischbach, Fridtjof Betz, Lukas Rebholz +6
The transition matrix (T-matrix) is a complete description of an object's linear scattering response. As such, it has found wide adoption for the theoretical and computational desc…
Modal Analysis of Gyrotropic Waveguides
Konstantinos Delimaris, Georgios D. Kolezas, Carsten Rockstuhl +1
We report on the modal analysis of open gyrotropic waveguides (GWs). The GWs consist of a non-circular gyrotropic (i.e., gyroelectric and gyromagnetic) core and an infinitely exten…
Oblique Multiple Scattering by Gyrotropic Cylinders
Grigorios P. Zouros, Konstantinos Delimaris, Carsten Rockstuhl +1
In this work, we develop a full-wave vectorial solution for the 2.5-dimensional (2.5-D), i.e., at oblique plane wave incidence, electromagnetic (EM) multiple scattering (MS) by a c…
Disordered Optical Metasurfaces: Basics, Properties, and Applications
P. Lalanne, M Chen, C. Rockstuhl +3
Optical metasurfaces are conventionally viewed as organized flat arrays of photonic or plasmonic nanoresonators, also called metaatoms. These metasurfaces are typically highly orde…
Electromagnetic Multipole Theory for Two-dimensional Photonics
Iridanos Loulas, Evangelos Almpanis, Minas Kouroublakis +3
We develop a full-wave electromagnetic (EM) theory for calculating the multipole decomposition in two-dimensional (2-D) structures consisting of isolated, arbitrarily shaped, inhom…
