- Аннотация: The boundary value problem of diffraction electromagnetic waves on a 3-dimensional inhomogeneous dielectric body in a free space is considered. This problem is reduced to a volume singular integro-differential equation. The smoothness properties of solutions of the integro-differential equation are studied. It is proved that for smooth data the solution from L2 will necessary be continuous down to the boundary of the body and smooth inside the body. The smoothness properties allow one to prove the equivalency between the boundary value problem and the integro-differential equation. In addition, using pseudodifferential operators calculus, an asymptotic expansion of the operator’s symbol is obtained and ellipticity and Fredholm property with zero index of the operator of the problem are proved.
