The main question remains when one should use RCWA or the C method. Al-though both methods have a completely different approach for solving the grating problem, it is widely known, that solving eigenvalue problems is the most computationally expensive operation in both …

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.
WebOct 1, 2012 · Abstract. We describe S 4, a free implementation of the Fourier modal method (FMM), which has also been commonly referred to as rigorous coupled wave analysis … WebFDTD and RCWA both model the same underlying physical laws. However both solve the Maxwell equations via a different mathematical and numerical approach. In FDTD the Maxwell equations are discretized directly in both time and space. RCWA first transforms the equations to the frequency domain (both time-frequency and spatial frequency).
WebSolved the problem of designing a crystal with high absorption at two frequencies. The optimization problem was preceded by an understanding of the Rigorous Coupled Wave Analysis (RCWA) method in order to analyze the absorption properties of the crystal. A variety of crystal patterns were explored during the process.
