Synthesis of an electromagnetic pulse generator

The cylindrical antenna, driven at its center by some transient voltage source and symmetrically loaded with lumped resistors, has been found to be a useful electromagnetic pulse generator. In this study a synthesis procedure was developed that yields the resistor values required to load the antenna so that, when an appropriate causal voltage source is applied to the center terminals of the antenna, the radiated electric field transient will approximate some prescribed fast-rising generally decaying function of time.
