Dyakonov surface waves
WebWe investigate the conditions necessary for the existence of Dyakonov surface waves (DSWs) propagating along the interface of a plasma metamaterial (PMM) and an isotropic dielectric material in the terahertz region. We assume the PMM to be a multilayer structure that consists of plasma and background isotropic material alternately. WebJan 4, 2024 · a Schematics of surface Dyakonov-Cherenkov radiation. A swift charged particle moving in a structure made of semi-infinite isotropic and birefringent material excites Dyakonov surface waves, leading to surface Dyakonov-Cherenkov radiation. b Radiation pattern of surface Dyakonov-Cherenkov radiation.
