Reflectionless absorption of electromagnetic radiation at its falling at an angle on the clarified swallowing wafer R. M. Kasimov, S. R. Kasimova Institute of Chemical Problems, 29 Javid av., Baku, AZ1143, Azerbaijan E-mail: ITPCHT@itpcht.ab.az chem@science.az Conditions of occurrence complete reflectionless absorption of an electromagnetic wave at its falling at an angle on swallowing wafer of an infinite thickness with the layer put on it not swallowing dielectric are found. <...> Their dependence on a thickness of a layer of a clarifying coating, an angle of incidence of a wave and dielectric properties of a material of a wafer and a coating are researched. <...> Исследуются их зависимость от толщины слоя просветляющего покрытия, угла падения волны и диэлектрических свойств материала подложки и покрытия! <...>
