Abstract :
The problems of plane wave scattering by resistive- and dielectric-strip gratings are considered. The formulation involves a set of resistive-type boundary conditions that characterizes nonzero jumps in tangential field components. The method of solution is based on analytical inversion of the static part of the full-wave equations and results in a rapidly convergent numerical algorithm. The dependences of the transmitted, reflected, and absorbed power fractions on the electrical and material parameters are presented
