Quick start
To run the model, open grating2D.pro or grating3D.pro with Gmsh.
Additional information
The 2D model applies to so-called mono-dimensional grating, i.e. structures having one direction of invariance. Various geometries and materials can be handled. The two classical polarization cases, denoted here E// and H//, are addressed [1], as well as the conical vector case. The 3D vector model applies to crossed-gratings having two directions of periodicity [2,3].
