Abstract

We present some formulas derived from the developed boundary integral equation theory, which are important for calculations of the efficiency, absorption, and polarization angles of gratings in conical diffraction. Examples of efficiency computations of X-ray grazing-incidence, high-conductive anomalously absorbing, high-spatial-frequency deep transmission, and cross-polarized symmetrical-groove-profiled gratings are considered. The solver tested has been found universal and accurate for calculating various off-plane diffraction problems.
