Problem of diffraction of electromagnetic waves on a 3D inhomogeneous anisotropic dielectric partially shielded body considered. The problem is reduced to a system of singular integro-differential equations. The operator of the system is treated as a matrix pseudodifferential operator (ΨDO) in Sobolev spaces. Using pseudodifferential operators calculus, ellipticity of the operator of the problem is...
The scalar problem of diffraction from a system of screens and bodies in quasi-classical statement is considered. The boundary value problem leads to a system of integral equations on two- and three-dimensional manifolds with boundary. The equivalence of the integral and differential formulations of the problem is established; the Fredholm property and invertibility of the matrix operator are proved...
The three-dimensional vector problem of electromagnetic wave diffraction by systems of bodies and screens of irregular shapes is considered. The original boundary value problem for Maxwell's equations is reduced to a system of integro-differential equations. The system of linear algebraic equations is obtained using the Galerkin method with compactly supported basis functions. The subhierarchi-cal...
