Reflectionless Incidence of the p-Polarized Electromagnetic Wave Through Solid-State Structure “Coating-Uniaxial Plasmonic Metasurface-Dielectric-Metal”

Abstract

In this work we studied the effects which occur during the incidence of p-polarized electromagnetic wave on the solid-state structure “coating-uniaxial plasmonic metasurface-dielectric-metal”. The purpose of this work is researching how the coating influences the effect of reflectionless incidence of the p-polarized electromagnetic waves on the solid-state structure “uniaxial plasmonic metasurface-dielectric-metal”. Numerical modelling was used to find the conditions that lead to reflectionless incidence of the p-polarized electromagnetic wave on the solid-state structure under consideration. Using this method we determined the parameters of the coating which are required to observe incidence of p-polarized waves with no reflection. It was found that dielectric coating of the solid state structure significantly changes the behavior of the effect. We showed that dielectric permittivity of the coating changes the frequencies at which reflectionless p-polarized waves occur. The dependency was established between permittivity and thickness of the coating which causes the effect of the reflectionless incidence of p-polarized waves. The conducted research has a great scientific and practical interest. The solid-state structure that was studied can be applied for designing conceptually new types of nanoelectronic and optical devices.
