Abstract
An electromagnetic energy source for emitting pulses of electromagnetic energy includes a sonde assembly and an energy storage capacitor. The energy storage capacitor has an electrode mounted in the sonde assembly and operable to generate an electric field, and a capacitive charge storage medium surrounding the electrode. A communication cable extends through a tubular member to the electrode. A fast-closing switch is positioned such that when the fast-closing switch is in a closed position, a circuit is formed that discharges the electrode.
