Recently, various industries have developed electro magnetic wave devices for commercial use. In the automobile industry, the electromagnetic wave technology is widely applied to wireless communication technologies such as ETC, GPS, VICS and digital terrestrial broadcasting and autonomous sensors such as millimeter-wave radar, tire pressure monitoring system and light sensor. A structural optimization method is expected for a functionality improvement of electromagnetic wave device however some problems concerning optimization method lead to wrong solution in the case of the electromagnetic analysis. This research deals with a structural optimization method for the electromagnetic analysis and some numerical examples included from radio-frequency devices to optical devices are presented.
