It … WebAug 9, 2016 · Rigorous Coupled-Wave Approach (RCWA) has been used successfully and accurately to study simple grating structures, such as one-layer gratings, one-whole gratings. In this paper, RCWA is expanded to solve Sandwich gratings (SG), which is composed of two identical planar dielectric gratings adjoined by thin metallic or dielectric film. WebRCWA computations are carried out in discretized reciprocal space, so a grid is required. The grid can be discretized by 2π/a, where a is the lattice constant of the 2D unit cell. One has to specify the direction of the impinging plane wave by θ and α, as well as the lattice constant in x and y ax and ay. iman fase
