We study also the amplitude peak with respect to other parameters such as : the number of antennas of the TRM, the pulse length (bandwidth), the polarization. We also focus on the TR when only a window of the transient response is time flipped. The combination of TR technique and reverberant chamber leads to make a high amplitude pulse generator from a low power arbitrary waveform generator. The potential application of this work could be the development of an “electromagnetic bazooka”, a non-nuclear electromagnetic pulse (NNEMP) weapon.
