Inverse-Designed Time-Varying Multilayers for Programmable Frequency-Momentum Light Scattering

Mohammad M. Asgari, Viktar Asadchy

Space-time-varying electromagnetic structures unlock wave-control mechanisms inaccessible to static media, including frequency conversion, harmonic generation, and joint control ov…

Metacrystals: Inversely-designed 3D-printed intelligent panels for 6G communications

Mohammad M. Asgari, Peter B. Catrysse, Shuai S. A. Yuan +3

Metasurfaces represent a promising platform for improving coverage in future communication systems. Passive designs are especially attractive because they need no power supply and…

Nanoscale optical nonreciprocity with nonlinear metasurfaces

Aditya Tripathi, Chibuzor Fabian Ugwu, Viktar S. Asadchy +6

Optical nonreciprocity is manifested as a difference in the transmission of light for the opposite directions of excitation. Nonreciprocal optics is traditionally realized with rel…

Light control with Weyl semimetals

Cheng Guo, Viktar S. Asadchy, Bo Zhao +1

Weyl semimetals are topological materials whose electron quasiparticles obey the Weyl equation. They possess many unusual properties that may lead to new applications. This is a tu…

Non-trivial point-gap topology and non-Hermitian skin effect in photonic crystals

Janet Zhong, Kai Wang, Yubin Park +4

We show that two-dimensional non-Hermitian photonic crystals made of lossy material can exhibit non-trivial point gap topology in terms of topological winding in its complex freque…

Three-dimensional random dielectric colloid metamaterial with giant isotropic optical activity

Viktar Asadchy, Cheng Guo, Ihar Faniayeu +1

Motivated by the theoretical observation that isotropic chirality can exist even in completely random systems, we design a dielectric metamaterial consisting of a random colloid of…
