UNIGIT is a sophisticated diffraction solver code for gratings with periodicity in one (line gratings)or two dimensions (crossed gratings). It is based on Lifeng Li's RCWA-approach or as he calls it MMFE (modal method with Fourier expansion). The code offers a variety of unique features. It is recommended to check it out just by downloading and running the Demo code.

UNIGIT is a universal grating solver that is based on two solving methods:

" the Rigorous Coupled Wave Approach (RCWA)
" the Rayleigh Fourier Method

In addition to that the solving methods are embedded in a matrix scheme. This matrix scheme permits the step-by-step solution of general layer stacks. A general layer stack can comprise different types of layers. These layer types are detailed in this document.
