The electric field integral equation (EFIE) with the method of moments (MoM) is used for treating problems of a thin wire antenna in the presence of a conducting cube. Pulse-expansion and point-matching technique in MoM are applied to both thin wire and closed object. For simplicity and efficiency, hybrid method for calculating near field and more importantly the surface field of objects is presented. Several examples in this paper show the validity of the proposed pulse-expansion and point-matching technique and the simplified hybrid calculation method.
