Using explosive devices to convert chemical/mechanical energy to electrical energy enables non stationary HPM and UWB sources to generate electromagnetic fields for destructive electronic interactions. Because these sources are intended to be near the target, the effective source-sink distance need not be as high as in stationary systems. Whether using the intrinsic antenna of these devices or external ones, the antenna indicates to be a key element to enlarge the ssd. The Comparison of destruction parameters of a test system in combination with typical source- and antenna parameters show similar ssd for HPM and UWB systems. However due to the wide range of destruction parameters of different target systems this statement cannot be generalized. The drawbacks and advantages of either source types according to the coupling efficiency for highly resonant targets or to the variation in the angle of incidence are the same as for stationary systems.
