In the present work, we treat a coated-optics problem in which it is required to choose an optimal refractive index of intermediate layer in a three-layer medium providing for maximum transmission of radiation through the medium. The extremum problem is considered as a formulation of the inverse problem for the stationary radiation transfer equation with generalized matching conditions for the Fresnel reflection-refraction at the interfaces between the media. Some analytical solutions are obtained.
