Wideband High Power Microwave Coupling Analysis of Automotive Engine

Coupling currents of key wires fixed on an automotive engine were simulated under the consideration of wideband high power microwave (HPM). An electromagnetic model of an automotive engine was built with the consideration of wires connected camshaft and injector separately. Simulation results show that coupling currents are much larger than the working currents of electric devices, and disturbances' frequency characters contain the resonant characters of wires and the spectrum of wideband HPM.
