General closed-form PML constitutive tensors to match arbitrary bianisotropic and dispersive linear media

The perfectly matched layer (PML) constitutive tensors that match more general linear media presenting bian-isotropic and dispersive behavior are obtained for single interface problems and for two-dimensional (2-D) and three-dimensional (3-D) corner regions. The derivation is based on the analytic continuation of Maxwell's equations to a complex variables domain. The formulation is Maxwellian so that it is equally applicable to the finite-difference time-domain (FDTD) or finite-element (FEM) methods. It recovers, as special cases, previous anisotropic media formulations, and dispersive media formulations.
