High‐Efficiency Multi‐Level Beam Switching with Single‐Gate Tunable Metasurfaces Based on Graphene The growing demand for ultra-fast telecommunications, autonomous driving, and futuristic technologies highlights the crucial role of active beam steering at the nanoscale. This work theoretically pre...

Super nice paper on highly efficient tunable metasurfaces by authors from Korean Institute of Science and Technology #KIST! Uses #RieszProjection and #PolesAndZeros in the #numerical analysis and #optimization doi.org/10.1002/adom...

Poles and zeros in non-Hermitian systems: Application to photonics Resonances are essential for understanding the interactions between light and matter in photonic systems. The real frequency response of the non-Hermitian systems depends on the complex-valued resonan...
