N2 - For a system of electrodynamic equations, the inverse problem of determining an anisotropic conductivity is considered. It is supposed that the conductivity is described by a diagonal matrix (Formula presented.) outside of the domain (Formula presented.), and the permittivity ε and the permeability μ of the medium are positive constants everywhere in (Formula presented.). Plane waves coming from infinity and impinging on an inhomogeneity localized in Ω are considered. For the determination of the unknown functions (Formula presented.), and (Formula presented.), information related to the vector of electric intensity is given on the boundary S of the domain Ω. It is shown that this information reduces the inverse problem to three identical problems of X-ray tomography.
