Abstract. In this paper various methods of reducing the size of holographic masks are proposed and their effectiveness is assessed. A method for diffraction calculation, suitable for use in layered structures of such masks, is proposed. A software module that allows to calculate the transmission and reflection of a plane wave of arbitrary polarization on periodic inhomogeneous medium with a cylindrical structure is developed. This software module is intended to be used for the study of applicability limits of some approximate methods for solving diffraction problems. The developed methods and programs have also been used to solve problems in other fields of electrodynamics, for example, in the problem of ocean surface radiolocation. Mathematical modeling of effects such as Brewster angle and Wood's anomaly was performed with the resulting software module. Quantitative modeling results are coincide with the analytical formulas with good accuracy.

Key words: diffraction, holography, radiolocation.
