In this paper, the influence of plane waves on scattering characteristics of a convex body was researched. The conducting sphere with dielectric coat was chosen as a convex body. The authors offer the method of indirect definition of conditions, in which plane waves are generated on a spherical structure and promote reducing of reflection by sphere. The frequency range, which correspond the generating of plane waves in flat stricture, was calculated. Then the reflection power of microwaves from that structure was calculated. After that, the reflection power of microwaves from perfect conducting sphere with same dielectric coat was calculated. The calculation done for several values of radius to compare results. The results were analyzed.
