The response of a short single-wire line excited by EMP was theoretically investigated and experimentally validated by means of an EMP simulator.A modified bounded-wave EMP simulator was developed with a rise time less than 5 ns and pulse width about 200 ns for the short line validation test.Comparison of current responses at the line termination between calculation using the transmission line theory and experimental measurement were presented.The good agreement shows that this bounded-wave EMP simulator can be used for short single-wire line experiment.This method of effects experiment has the characteristics of reasonably uniform electromagnetic field distribution in the working volume,easy adjustment of EMP experiment parameters and convenience to measure electric field and current response,etc.
