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…
Reflectionless Programmable Signal Routers
Jérôme Sol, Ali Alhulaymi, A. Douglas Stone +1
We demonstrate experimentally that reflectionless scattering modes (RSMs), a generalized version of coherent perfect absorption, can be functionalized to perform reflectionless pro…
An optic to replace space and its application towards ultra-thin imaging systems
Orad Reshef, Michael P. DelMastro, Katherine K. M. Bearne +4
Centuries of effort to improve imaging has focused on perfecting and combining lenses to obtain better optical performance and new functionalities. The arrival of nanotechnology ha…
