      Abstract
      The accuracy of the magnetic-field integral equation (MFIE) for the Method of Moments (MOM) and fast-multiple-method (FMM) solutions of the electromagnetic scattering problems modeled by abitrary planar triangulations is improved by the choice of basis functions. The four different basis functions, Rao-Wilton-Glisson (RWG), TL, n × RWG and n × TL are used to define the planar triangles. The current distribution and the radar cross section (RCS) results are found to be more accurate for the TL and n × TL functions. TL and n × TL functions are used to improve the efficiency inspite of the increased computational cost.
