Karazin popup.description2 The strict decision of diffraction problem of - and - polarized waves by infinite periodical grating without one strip was built. The currents on strips are represented in the form of two summand: currents of infinite periodical grating and correction current caused by lack of one strip. The spectral function of correction field and Fourier's amplitudes of scattered field of infinite periodical grating were defined from singular integral equations with additional conditions. The numerical decision with method of discrete singularities was received. The venetian blind-type fractal gratings with modified end based on pre-Cantor set for formation required effective scattering area of object were offered. The resonant parameters of new tunable grafen reflecting grating were investigated. The procedures of UHF structures analysis was created. Product Description popup.authors Є.Шаулов І.Варакін А.
