✦ Synopsis
Analytical expression for the reflection transmission coefficients of one-dimensional diffraction gratings with the elements shaped as free-space metal circular cylinders, metal plane strips, and plane strips on a dielectric substrate are presented in a low-frequency approximation. For the strip grating on a substrate, an analysis of the accuracy of asymptotic characteristics is carried out by a comparison with results of the accurate numerical solution of the diffraction problem. Characteristics are calculated for a wide range of geometrical parameters corresponding to typical practical geometries of gratings, which are used in quasioptical de¨ices of millimeter-and submillimeter-wa¨e ranges, and are accompanied by a re¨iew of experimental data.
