Numerical method of applying shadow theory to all regions of multilayered dielectric gratings in conical mounting

摘要: Nakayama’s shadow theory first discussed the diffraction by a perfectly conducting grating in planar mounting. In theory, new formulation use of scattering factor was proposed. This paper focuses on middle regions multilayered dielectric placed conical Applying to matrix eigenvalues method, we compose transformation and improved propagation matrices for Using these factors, being basic quantity amplitudes, formulate description three-dimensional fields which is available even cases where are degenerate any region. Some numerical examples given regions.
