Asymptotic phasefront extraction applied to electromagnetic scattering predictions

摘要

In this paper the APEx-MoM is extended to use linearly phased Rao-Wilton-Glisson (LP-RWG) basis functions in the smooth regions, and applied to some realistic geometries. The scaling of the number of unknowns with frequency is asymptotically linear because only the edge regions need to be re-meshed with conventional basis functions as the frequency increases.
