Electromagnetic radiation system (EMRS) for susceptibility testing

The function of the Electromagnetic Radiation System (EMRS) is to generate electromagnetic energy so as to produce a constant field strength that can be automatically scanned as a function of frequency. The design objective is to cover the frequency range of 30 hertz to 40 gigahertz with field strength intensities up to 200 volts per meter. A stripline approach is described and proposed for use as the field generating device for the lower frequencies. The use of defocused parabolas are proposed for use at the higher frequencies. The final system configuration is described including specific equipment to be used along with interface and control circuitry necessary for proper operation.
