| Abstract: | Electromagnetic scattering problems containing subregions which are electrically small but geometrically complex are examined. By utilizing quasi-static methods for the small regions, full-wave methods in the remaining region, and determining necessary coupling relations between the small regions and the overall geometry, a considerable improvement in numerical efficiency is realized. The particular method developed here is valid for quasi-static regions in which magnetic induction can be ignored. Results using the proposed method have been obtained for a pair of closely spaced collinear wires. A comparison of these results with the wire antenna code, MININEC, showed excellent agreement |
