It was shown that powerful microwave radiation strongly changed the number of dislocations in a surface layer. This could occur only in the case where a considerable fraction of the incident energy was absorbed in a metal, but this contradicted well-known facts concerning the essentially complete reflection of microwaves from metallic surfaces. All of these facts demonstrated that the absorption and reflection of a high-power microwave signal by media with a high conductivity were apparently different at low and moderate power levels, where complete accord between theoretical and experimental results existed. An attempt was made to furnish a physically correct interpretation of the observed phenomena.
