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. Websystems obtained with RCWA, but when RCWA uses q layers it also has q eigenvalue systems. Altogether, this implies that RCWA may have 8 times more layers than the number of media for the C method to have an equal number of computations. 4 Results To show the results, test case 2 from [2] has been used.
