a Illustrates the model used in simulations for the closed door scenario. b The model of the open door scenario where the vehicle doors are removed. c The electric field magnitude plot for a closed door model at resonance. d The electric field magnitude plot for a open door model at resonance. e Voltage channel loss versus frequency for open versus closed door.
