Paraboloidal and prolate-spheroidal impulse radiating antennnas with illustrative examples

We start this paper with a four-band classification of high-power electromagnetic (HPEM) waveforms based on bandwidth that has been recently proposed and formalized. An antenna system that radiates impulse-like waveforms making use of reflectors has been called the impulse radiating antenna (IRA). More recently prolate-spheroidal surfaces are being considered to fabricate such antennas for specialized applications. This paper presents these antennas along with some representative applications.
