Although today, these methods are also often called Fourier modal methods (FMM), we would prefer here their original name stemming from the diffraction grating analysis. The importance of these frequency-domain rigorous techniques has been even increased, as a plethora of novel designs of nanophotonic and nanoplasmonic structures is increasingly growing, not only bringing new physics into life, but also attracting photonics devices applications. As had been demonstrated, the original periodic RCWA method has become applicable also to modeling isolated structures, as photonic waveguides and cavities; these isolated objects being considered as a single period of "supergrating", with a proper separation of neighboring "superperiods" in contrast to coupling in standard periodic structures. The extensions and ingredients primarily include, mostly, e.g. various correct (or fast) Fourier factorization schemes, adaptive spatial resolution techniques, symmetry considerations, incorporation of general fully anisotropic materials, as well as various variants of boundary conditions and correct field calculation procedures. Finally, several alternative approaches / modifications to several critical parts within the algorithm, which can improve the algorithm performance, in terms of time efficiency and / or computational requirements, will be presented. In previous couple of years, we have developed in-house 2D and 3D numerical tools based on RCWA / aRCWA methods for the analysis of nanophotonic and nanoplasmonic structures and systems.
