Widespread use of layered media causes study of their characteristics. However, to date only a small number of dependencies of material layer parameters on the spatial coordinates have been known when it is possible to obtain analytical solutions describing the wave processes occurring in them. The paper presents a layered Green's affinor area. Built Green's tensors allow solving a wide class of problems of the spectral theory of electromagnetic waves diffraction on layered media.
