Influence of subwave details of microrelief on the diffraction pattern of gaussian beams

Abstract

The paper deals with the influence of subwavelength details with two types of etching of microrelief (ridge and groove) on the diffraction pattern. Modeling the diffraction of uniform-polarization radiation corresponding to both a Gaussian beam and a vortical Gaussian-Laguerre beam is performed by the method of solving Maxwell equations by finite differences in time domain (FDTD). The characteristics and features of the diffraction pattern in the near zone, including those connected with the formation of the longitudinal component of the electric field are determined.
