Abstract :
Methods for solving the electromagnetic scattering from bodies with sub-wavelength features are well established. However their application is limited to PEC scattering bodies, whilst when applied to lossy or conducting materials they become inefficient and less desirable. In this paper we extend the capabilities of these fast methods to solve for non-perfect conductors by using the approximation of the Impedance Boundary Condition.
