The SWO Box, a Portable Resonant Source for High-Power Electromagnetic Applications

Experimental results of a portable and compact high power electromagnetic, mesoband radiator, working in the lower-UHF band, are presented. The radiator is a self-contained unit, comprising a quarter-wave switched oscillator (SWO), antenna, high-voltage source, pneumatic system, and battery bank. The TEM horn antenna acts a mechanical support and partially houses the components of the system. The bounding box of the system is 0.44 λ at the central frequency of operation. Measurements of the radiated electric field are presented, and the overall performance of the system is discussed.
