Abstract
Conference Title: 2017 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD) Conference Start Date: 2017, July 24 Conference End Date: 2017, July 28 Conference Location: Copenhagen, Denmark We introduce a general approach to study diffraction harmonics or resonances and resonance conditions for blazed reflecting gratings providing knowledge of fundamental diffraction pattern and qualitative understanding of predicting parameters for the most efficient diffraction.
