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…
Anisotropic Virtual Gain and Large Tuning of Particles' Scattering by Complex-Frequency Excitations
Grigorios P. Zouros, Iridanos Loulas, Evangelos Almpanis +2
Active tuning of the scattering of particles and metasurfaces is a highly sought-after property for a host of electromagnetic and photonic applications, but it normally requires ch…
Tunable all-optical logic gates based on nonreciprocal topologically protected edge modes
Jie Xu, Panpan He, Delong Feng +4
All-optical logic gates have been studied intensively for their potential to enable broadband, low-loss, and high-speed communication. However, poor tunability has remained a key c…
Highly Directional Scattering of Terahertz Radiation by Cylinders using Complex-Frequency Waves
Iridanos Loulas, Grigorios P. Zouros, Evangelos Almpanis +1
In this study we investigate the directional scattering of terahertz radiation by dielectric cylinders, focusing on the enhancement of directionality using incident radiation of co…
Unidirectional guided-wave-driven metasurfaces for arbitrary wavefront control
Shiqing Li, Kosmas L. Tsakmakidis, Tao Jiang +5
Metasurfaces, composed of subwavelength electromagnetic microstructures, known as meta-atoms, are capable of reshaping the wavefronts of incident beams in desired manners, making t…
Three-Dimensional Invisibility to Superscattering Induced by Zeeman-Split Modes
Grigorios P. Zouros, Georgios D. Kolezas, Evangelos Almpanis +1
We report that the fundamental three-dimensional (3-D) scattering single-channel limit can be overcome in magneto-optical assisted systems by inducing nondegenerate magnetoplasmoni…
