cqvip:1 Introduction and Main Results LetΩ■R^(d),d=2,3,be a bounded Lipschitz domain,multiply connected.LetΓdenote the boundary ofΩ,with a finite number of connected componentsΓ_(i),1≤i≤N_Γ,where N_(Γ)is an integer number.LetΩbe occupied with discontinuous,anisotropic and inhomogeneous media ofμ(magnetic permeability)andε(electric permittivity).
