Plasmonic coated scatterers for tunable coherent perfect absorption
Ali Ghorashi, Ali H. Alhulaymi, A. Douglas Stone
We derive, in closed-form, the surface conductivity required for coated subwavelength-scale spherical and cylindrical scatterers to perfectly absorb incident coherent light of fixe…

Coherent Control of Wave Scattering via Minimal-Parameter Tuning of Complex Spectra
Ali H. Alhulaymi, Nazar Pyvovar, Philipp del Hougne +2
We introduce and validate a theoretical framework for coherent control of multichannel linear scattering to route waves through complex geometries with multiple scattering. We show…

Agile Free-Form Signal Filtering with a Chaotic-Cavity-Backed Non-Local Programmable Metasurface
Fabian T. Faul, Laurent Cronier, Ali Alhulaymi +2
Filter synthesis is an inverse problem that is traditionally approached rationally by considering spatially disjoint resonators, approximating them as lumped elements, and engineer…
