Abstract :
A method of moments formulation is developed to analyze the scattering of corrugated surfaces by using an impedance boundary condition. The numerical analysis of the impedance surface is done using closed-form formulae and accurate numerical integration. The studied formulation greatly decreases the computational resources required to study corrugated structures.
