Some embodiments of the invention include a pre-pulse switching system. The pre-pulsing switching system may include: a power source configured to provide a voltage greater than 100 V; a pre-pulse switch coupled with the power source and configured to provide a pre-pulse having a pulse width of T.sub.pp; and a main switch coupled with the power source and configured to provide a main pulse such that an output pulse comprises a single pulse with negligible ringing. The pre-pulse may be provided to a load by closing the pre-pulse switch while the main switch is open. The main pulse may be provided to the load by closing the main switch after a delay T.sub.delay after the pre-pulse switch has been opened.

The power transistor is configured to supply a voltage to the load.

A dielectric structure is loaded with energy (e.g., charge), which is retained therein until a trigger causes rapid discharge of the loaded energy and generation of an accompanying electromagnetic pulse (EMP). By appropriate design of the dielectric structure and/or trigger, the waveform of the EMP resulting from the rapid discharge can be tailored. Features of the dielectric structure can be modified and/or other devices can be coupled to the dielectric structure to also tailor the EMP, for example, to provide directionality. A modeling unit can predict the discharge in the dielectric structure and/or resulting EMP. The modeling unit can be used to determine charge density spatial distribution within the dielectric structure, shape of the dielectric structure, and/or actuation timing/location necessary to yield a desired waveform for the EMP emanating from the dielectric structure upon discharge.
