The paper discusses a method for solving an integral equation for calculating a
three-dimensional electric field in a medium with a two-dimensional geometry based on the
Fourier transform. The results of the numerical solution of the transformed integral equation
and the original integral equation for the medium with the surface relief are compared. The
original equation was solved using parallelization technologies on a system with shared memory.
A significant performance improvement based on the transformed equations, including in
comparison with the parallel version of the program for the original integral equation, is shown
