A bounded wave transmission line type NEMP simulator-design, construction and field mapping

The important aspects in the design, construction and performance of a nuclear electromagnetic pulse (NEMP) simulator are described with considerations of (a) reliably simulating the NEMP environment in a limited experimental volume without nuclear detonation end, (b) to measure accurately the time varying E, D-dot and B-dot field waveforms by suitable non-interfering sensors. Plane-wave simulation of the radiated electromagnetic fields is done through the quasi-transverse electromagnetic (TEM) bound fields of the transmission line. An active volume of 300 mm (L)/spl times/150 mm (W)/spl times/50 mm (H) is chosen for electronic subsystems' and components' hardness/vulnerability assessment. The Bell Lab specified electromagnetic pulse waveform-the difference of two exponentials, is selected for synthesizing the circuit parameters of the transmission line guide.
