Calculation of Diffraction Efficiency for a Reflective Volume Holographic Grating generated by a Spherical Wave

In this Demo the diffraction efficiency of a volume holographic grating is investigated, which was generated by an impinging spherical and plane wave. The rigorous modeling solver FMM (RCWA) is applied for accurate calculation of the efficiencies. The rotation-symmetry of the setup is exploited, in order to significantly reduce the calculation time.
