Nonlinear metamaterial absorbers enabled by photonic doping of epsilon-near-zero metastructures
Nahvi, Ehsan; Liberal Olleta, Íñigo ; Engheta, Nader (American Physical Society, 2020) Artículo / ArtikuluaWe theoretically demonstrate an approach for designing absorbers with strongly intensity-dependent absorption. The proposed absorbers consist of a spacer layer between a top resistive sheet and an underlying metallic ... -
Soft surfaces and enhanced nonlinearity enabled via epsilon-near-zero media doped with zero-area perfect electric conductor inclusions
Nahvi, Ehsan; Liberal Olleta, Íñigo ; Engheta, Nader (Optical Society of America, 2020) Artículo / ArtikuluaIntroducing a dielectric inclusion inside an epsilon-near-zero (ENZ) host has been shown to dramatically affect the effective permeability of the host for a TM-polarized incident wave, a concept coined as photonic doping ...
