Electromagnetic Waves

The authors present a relatively simple, computer-oriented, general and unified approach to the analysis of metallic antennas and scatterers (of electrically small and medium sizes), based largely on their own original work. The method appears to offer superiority over existing alternatives by circumventing most of the difficulties encountered by those methods. It should be of considerable importance to working antenna engineers and researchers.
