摘要
This letter presents a novel approach to simulate materials with arbitrary properties, in particular good conductors, in a boundary integral equation context. The advocated differential surface admittance operator permits the replacement of the material by the background medium through the introduction of an equivalent surface current density. A formulation based on the eigenfunctions of the volume is constructed and successfully demonstrated through scattering at a conducting cylinder and through the analysis of a lossy dipole antenna.
