## Abstract

This letter solves the volume electric current integral equation (VJIE) using the hybrid Full- and Half- Schaubert-Wilton-Glisson (SWG) basis functions for inhomogeneous dielectric objects. Techniques are developed for dealing with the discontinuity of equivalent volume electric currents on the interface between two media. Numerical results show that the VJIE discretized with the SWG basis functions (JSWG) has much faster convergence solution than the traditional volume electric flux (D) integral equation (VDIE), especially for relatively high-permittivity objects, while maintaining the same accuracy. Moreover, for the same mesh, the presented JSWG scheme needs much fewer number of unknowns compared to that of the VJIE using the constant vector basis functions (JConstBasis) for piecewise homogeneous dielectric objects problems.
