Abstract :
This paper quantifies the computational efficiency of the extended, three-dimensional Stationary Phase Method, enhanced by Fresnel functions (3D-SPM-F). This method was recently developed by this research group for the fast, yet accurate characterization of electromagnetic scattering from finite, perfectly conducting (PEC) plates. The improvement in computational cost is demonstrated via comparison to standard numerical integration, as well as to an integral equation technique.
