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.
WebFeb 27, 2024 · Rigorous coupled-wave analysis (RCWA) is a very effective tool for studying optical properties of multilayered vertically invariant periodic structures. However, it fails to deal with arrays of small particles because of high gradients in a local field. In this paper, we implement the discrete dipole approximation (DDA) for the construction of scattering … WebDec 3, 2016 · Most recent answer. You do not need RCWA for this.
