Abstract :
This paper presents the extension of the method of moments (MoM) and multilevel fast multipole method (MLFMM) in FEKO to include higher-order basis functions (HOBFs) on curvilinear triangular patches. HOBFs reduce the number of unknowns, memory and run-time compared to the traditional planar Rao-Wilton-Glisson (RWG) basis functions.
