UNIGIT is an universal rigorous grating solver based on the RCWA, C-method (coordinate transformation) and the RF (Rayleigh-Fourier) method. There are four different solvers implemented:

- RCWA/RF based for 1D classical mount including slanted layers ;
- RCWA/RF based for 1D conical mount including slanted layers ;
- RCWA/RF based for 2D +accelerators ;
- C-method based for non-parallel multilayer gratings.

All installation packages of UNIGIT can be run as Demo's with reduced functionality - see download page.

UNIGIT version v.2.01.04 alpha is available now. The most important new features are: the new cross section viewer showing the whole multilayer stack, the color coding option for materials and n&k files, the extension of the 1D RCWA solvers to cover slanted (skewed) layers and the Python link which enables to run Python scripts calling Unigit functionality directly.

Besides, it includes of course all the nice features of version 2.01.03 such as parallelization by multi-processing , a symmetry accelerator for symmetric 2D setups, a genuine C-method based solver for multilayer 1D gratings with non-parallel interfaces, the Unigit project mode option to retrieve information of older computations, a fast diffraction angles computation and a file controlled flexible looping . Please ask for a quotation.
