Recent advances in electrically small antennas have been proposed for a range of communications applications. In general these antennas have wide impedance bandwidths, but low efficiency and power handling capabilities. Recently members of our team at the University of Arizona have developed a class of efficient electrically small antennas (EESAs) that we call the EZ antenna that gets around these limitations through careful design of the space-loading of the antenna. The loading strategies we have pursued are based on advances in the field of metmaterials. We have designed and built prototype systems throughout the 100 MHz"10GHz frequency rantes, but our designs have not been optimized or tested for HPM applications. In this proposal, we seek to alter the strategies proposed for low-voltage electrically small geometries and adapt them to handle high input voltages and powers.

The proposed effort is to develop a frequency and waveshape agile pulse forming system. The pulse forming system is based on a Blumlein topology and allows a wide range of waveforms to be generated from a fixed set of mechanical hardware.

ASR proposes to develop an HPM source for deployment into the MLRS M26 (or smaller) payload bay. Multiple, parallel FEGs will charge a single quarter wave oscillator to 100kV or more, and each FEG will be fired in order to accomplish the desired pulse repetition rates (PRR) in excess of 100 Hz. When the oscillator is fully charged, an internal switch closes and the oscillator will begin to oscillate with the chosen antenna load to generate a wideband radiated signal. A secondary prime power supply will be based on thermal batteries for those applications in which explosives are not appropriate.

The Navy has a need to control such extreme power specifications that no suitable switches exist. The Navy power specifications require us to develop a novel medium (probably a pressurized gas or liquid) that can be configured to meet the requirements and control the flow of electrical power directly. Our extensive switching expertise has allowed us to develop a series of novel test fixtures and to perform a series of preliminary experiments to explore a wide variety candidate mediums during the Phase 1 base.
