Abstract

Abstract In recent, the requirements for the safety to the effects of high power electromagnetic wave have been increased along with the development of electricity and electronic equipments. The small sized electronic devices and the various components have been analyzed by using the full-EM simulation and solving a complete set of Maxwell equation. However, the deterministic approach has a drawback and much limitation in the electromagnetic analysis of an electrically large cavity with a high complexity of the structure. In this paper, statistical theory and topological modeling method are combined to analyze the large cavity with a complex structure. In particular, the PWB(Power Balance) method and BLT(Baum-Liu-Tesche) equation are combined and employed to solve the frequency response to the large-scaled cavity with remarkably reduced time-consumption. For instance, a PCB substrate inside box of box are considered as a large structure with a complexity.Key words: Power Balance Method, Electromagnetic Compatibility, BLT Equation, Topological Analysis, Full Wave Analysis rsiJtsi!puviJ#(Department of Electronics, Telecommunication and Computer Engineering, Korea Aerospace University) *ru vOw(Electronics and Telecommunications Research Institute)Manuscript received July 7, 2014 ; Revised September 5, 2014 ; Accepted September 11, 2014.
