The problem on the diffraction of an electromagnetic-wave packet from a transparency with periodic structure made of conductor and dielectric is analyzed. Series representing the solution of the rigorously formulated boundary problem for the wave equation are given in an analytic form. The problem of determining coefficients of a series is reduced to a stable procedure of solving a set of integral Fredholm equations of the second kind. The solution describing the optical field in the transparency is analyzed and used to formulate conditions for optimization of the transparency geometry and optical parameters of dielectric with respect to the contrast of the transmitted signal. The problem under consideration illustrates the general numerical analytic method used for solving problems of a similar class. 1 fig., 8 tabs.
