Webrcwa - Script command. RCWA. Calculates the reflection and transmission of a plane wave through a layered periodic media using the RCWA solver. This function returns the … WebFor any chosen required precision the RCWA calculation outperforms the FDTD package. The data show that for meta-surface calculations the RCWA method returns results faster than FDTD at the same accuracy. This speed does come at a cost, RCWA is only suited for periodic structures while the FDTD method can also be applied to non-periodic structures.

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. 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).
