The theory of scattering matrices and microwave network analysis are employed to solve the problem of scattering from cascaded infinite periodic gratings. The total reflection and transmission coefficients are calculated as functions of angle of incidence, wire spacing for each grating, grating separation, wire thickness, and number of gratings that comprise the cascaded structure. Moreover, the problem of stacking dielectric slabs with periodic gratings is formulated and solved. In all cases, the Secant Corrector Spectral Iteration approach is used as a numerical method for calculating the desired currents and fields.
Finally, calculated values of the reflection and transmission coefficients are presented and compared with other experimental and theoretical data.
