Electromagnetic Resonances in Complex Structures: Case of a Vehicle

In this paper, a study of the resonances occurring inside a vehicle has been carried out. The methodology used for this investigation is described in this paper. It consists in two main parts. Firstly, electromagnetic fields are computed in the vehicle using a numerical code based on the method of moments. The frequencies of the resonances are then identified by post-processing the computed results. The second part consists in the localization of the resonances inside the vehicle, which provides sometimes enough information to identify and explain their origins.
