Image Theory for DC Problems Involving a Conducting Half Space Bounded by theGeneral Anisotropic Impedance Surface

摘要

A novel image theory is introduced, applicable to DC problems involving currentsources in an isotropic conducting half space bounded by a planar, reciprocal, anisotropic impedance surface. The theory is a generalization of that involving an isotropic impedance surface and that involving a perfect anisotropic impedance surface with zero and infinite resistivities in two orthogonal directions on the plane, previously derived by these authors. The image for a point current source is a combination of an electric line current source and a transverse quadrupole magnetic line current source. The magnetic current component vanishes for vanishing anisotropy while the electric current component vanishes for perfect anisotropy.
