Analysis of electromagnetic wave in automotive cabin using complex Poynting's theorem

Due to the fast spread of the electric cars and the advanced driver assistance systems in recent years, it is necessary to reduce the electromagnetic noise from the power electronics, which are usually in high speed and with large electricity, and in the meantime to improve the immunity performances of sensing apparatus and communication equipment. The electromagnetic environmental compatibility in the cars will be of more importance in future. In this work, the behavior of electromagnetic waves generated in automotive cabin was estimated by a use of simulation techniques for the case where electromagnetic waves were irradiated into the simple cabin from outside, and we propose a new method to analyze electromagnetic waves propagating in automotive cabin by using Poynting's theorem.
