Exact solution of Maxwell’s equations is compared on representative two-dimensional model problem with solutions of simplified equations derived from different variants of high-frequency approximation. Comparison shows that for the considered problem derivatives accounting by angle variables in high-frequency approximation equations essentially expands time fields of application of this approximation.
