Understanding the HPM generation in atmospheric air with reference to small-size MCG

The theoretical model of the HPM generation is presented. The model suggests that the peak power can reach the theoretical value of 1.8 GW. The model yields the current waveform supplied by the generator to the HPM emitting structure that operates in atmospheric air. Comparison between the experiment and the theory is given. To get maximum radiating power from the system, it is suggested that the system must be designed to follow the concept of double resonance, put forward by Nikola Tesla.
