Diffraction of electromagnetic wave on multielement diffraction grating

The problem of plane-wave diffraction on a multielement grating of arbitrarily shaped cylindrical screens is rigorously solved using the integral equations technique. An integral representation of the Green's function of the problem is suggested. It substantially allows improvement of the calculation accuracy and effectiveness of solving. In the case of illumination by a normal E-polarized wave, a resonance penetration of it through the array is analyzed.
