REFLECTIONLESS ABSORPTION OF ELECTROMAGNETIC RADIATION IN ITS INCIDENCE ON THE TWO-LAYER SYSTEM DIELECTRIC-METAL AT AN ANGLEE. R. Kasimov UDC 621.365 A study is made of the conditions of occurrence of the total reflectionless absorption of electromagnetic radiation in its incidence, at an angle, on a layer of an absorbing dielectric applied to a metal substrate. The equations of the relationship between the selective values of the angle of incidence of the wave and the thickness of the coating layer and its dielectric properties for which we have the effect of total absorption of the incident wave with a different type of its polarization are obtained. The possibility of experimental observation of the indicated effect is considered.
