Modal methods feature an elegant and efficient way for solving photonic scattering problems with the help of the s-matrix algorithm. In this contribution, we will first give an overview over our current developments in the traditionally used Fourier modal method and present recent results for periodic as well as aperiodic structures like woodpile photonic crystals and liquid crystal based fiber gratings. However, for some applications it seems reasonable to replace the plane wave basis with a localized polynomial basis. This leads us to the B-spline modal method whose basic principles and particularities will be introduced in the second part.
