Coherent and Incoherent Phenomena in Anisotropic Periodic Gratings

Popis výsledku v původním jazyce

This paper deals with modeling of incoherent and partially coherent effects in structures with lateral periodicity based on scattering matrix formalism. The recurrent formulas are applied in matrix form to describe structures consisting of general anisotropic materials. Incoherent wave summation is presented in the form of infinite geometric series and generalized Mueller matrix calculus describing complete polarimetric response including depolarization phenomena. This method can be combined with any of the existing coherent methods of modeling periodic structures and it offers significantly faster computational performance than partially coherent/incoherent methods based on averaging. The general approach is demonstrated on phenomena emerging from the complex interaction between diffraction grating and thick substrate and the models are compared with experimental spectroscopic data.
