Maximization of injection energy during CS10 and CS11 EMP testing

摘要

Summary form only given. Subsystem testing for EMP, NEMP, andlightning is often performed by injecting damped-sinusoidal currents andvoltages in cables and pins entering the equipment or subsystem undertest (EUT). The relationship of the energy injected to an EUT and theenergy delivered to the EUT was addressed at the 1989 IEEE EMP Symposiumby R.M. McConnell. The authors claim that McConnell's treatment of theproblem contained a fundamental error. This supposed error is addressed.The energy is calculated, assuming three different configurations of theinput port under test. The present calculations imply that, in order tomaximize the energy delivered to a load Z_t via atransmission line with characteristic impedance Z_g,the source impedance must be minimized rather than matched to thecharacteristic impedance of the transmission line
