Abstract : Analytic evaluation of 'typical' Army cables demonstrates the coupling due to nuclear source-region EMP is sufficient to cause dielectric breakdown of the cable jacket dielectric, the air surrounding the cable, and, in some cases, the soil itself. The result of these nonlinearities is to greatly increase the late-time current that can be coupled into systems. The report presents the current waveforms induced on RG-8 and RG-58 cables exposed to high -altitude and source-region EMP environments over lengths of 100, 600, and 280 m. Experiments are suggested for validating some of the code assumptions.
