An electric field sensor which may be used to detect the electromagnetic pulse EMP which accompanies a nuclear explosion, as well as other pulsed electric fields, is disclosed. One embodiment of this sensor has been constructed with an overall dimension of less than 5 cm. In general a sensor can be built to conform to an arbitrarily shaped conducting surface such as an airplane surface. Because of this conformity the sensor does not perturb the electric field being measured. By building the probe so that its RC time constant is much greater than the pulse rise time the probe output voltage is self integrated, and produces an output that is proportional to the signal itself rather than to its derivative. The nondifferentiating or self-integrating feature allows full utilization of the sensoroscilloscope bandpass. Patents. RRH
