Experimental estimation of E-field distribution in a vehicle under multipath propagation environment using a reverberation chamber

In this paper, we describe the maximum electric field (E-field) distribution in a vehicle under multipath propagation and single plane-wave exposure environments, as a basic study on radiated immunity testing for vehicles. The experimental estimation of the spatial field under these environments is performed using a reverberation chamber and an anechoic chamber. Experimental results obtained using a 1/5-scale vehicle model show that the E-field level in the vehicle under single plane-wave exposure is approximately 6 dB larger than that under a multipath propagation environment.
