Abstract

A novel integral equation is proposed in this paper to solve electromagnetic scattering from objects with impedance surfaces. Derived from a new implementation of the impedance boundary condition (IBC), this integral equation is also able to calculate scattering from perfect electric conductor (PEC) and perfect magnetic conductor (PMC) objects if the surface impedance is set to zero or infinity. By including both the surface electric and magnetic currents as unknown quantities, the proposed formulation is a dual formulation of itself, and is free of spurious interior resonance corruption. Several examples are given to demonstrate the performance of the formulation.
