Abstract:
|
We show a novel integrating technique, the direct evaluation method, that provides maximum accuracy in the computation of the MFIE-interactions between neighboring noncoplanar basis functions sharing an edge or a vertex of the discretization. Unlike the previous techniques, this strategy requires no extraction of quasi-singular terms from the Kernel and accounts for both inner- and outer-integrals. We show that the
recently proposed discretization of the MFIE with orthogonal facet-oriented basis functions provide best accuracy in the RCS
computation of objects with small electrical dimensions when compared with other conventional basis functions sets. |
