PLANE-WAVE SCATTERING AND ABSORPTION BY RESISTIVE-STRIP AND DIELECTRIC-STRIP PERIODIC GRATINGS

The problems of plane wave scattering by resistive and dielectric stri p gratings are considered. The formulation involves a set of resistive -type boundary conditions that characterizes nonzero jumps in tangenti al field components. The method of solution is based on analytical inv ersion of the static part of the full-wave equations and results in a rapidly convergent numerical algorithm. The dependences of the transmi tted, reflected, and ab sorbed power fractions on the electrical and m aterial parameters are presented.
