Abstract

To effectively solve the electromagnetic scattering or radiation properties from the perfect electric conductor (PEC) objects containing closed-open surface junctions, how to establish the hybrid combined field integral equation-electric field integral equation (CFIE-EFIE) is studied, which is different with the existing scheme for the objects where the closed and open parts are separate. Further, it is found that when the integral equation is solved using the method of moments (MoM), if the widely used RWG basis functions are employed to expand the induced surface current, the CFIE-EFIE may give inaccurate numerical results for the objects containing fine structures. The numerical accuracy can be improved by introducing the linear-linear (LL) basis functions. Moreover, to pursue a high computational efficiency, the LL and RWG basis functions are simultaneously used to expand the current on the fine structures and other relatively smooth surfaces respectively, whose validity is verified by numerical results.
