The surface impedance - A pertinent parameter to describe finite conductivity materials in numerical codes
Abstract
This paper deals with the description of finite conductivity materials in numerical codes solving Maxwell's equations. It is shown that the surface impedance concept leads to a good representation in many practical cases, and numerical results are validated by comparison with analytical formulas. The applicability limits of the surface impedance modeling is finally discussed.
