A Onelab model for the parametric study of mono-dimensional diffraction gratings.
This document aims at presenting both theoretical and practical aspects of the grating_2D Onelab model (available at this http URL). This model applies to so-called mono-dimensional grating, i.e. structures having one direction of invariance. Various geometries and materials can be handled or easily added. The two classical polarization cases, denoted here E// and H//, are addressed. The output consists in a full energy balance of the problem computed from the field maps. This model is based on free the GNU softwares Gmsh, GetDP and their interface Onelab.
