Simulation of infinite periodic graphene planar grating in the THz range by the method of singular integral equations

Abstract

Plane wave diffraction by the infinite periodic planar graphene grating and infinite grating above a perfectlyconducting plane in the THz range is considered. The mathematical model is based on the graphene surface impedanceand the method of singular integral equations. A comparison with finite grating is made. Reflectance, transmittance,and absorbance are studied as a function of graphene and grating parameters.
