Photoconductive switch based HPM for airborne counter IED applications

We describe present work at Polarix on a photoconductive switch based HPM systems. We will describe some of the key elements of the technology and the system being developed. They include silicon backed biased junction switch technology and manufacture, low inductance-high current switch integration with thin film Blumlein type circuits, multi switch multi-cycle generation, and radiation concepts using asymmetric Wheeler-Chu apertures for side firing UAV platforms. We will also present experimental results showing switch data, radiator performance, and related data as time permits. We will also briefly describe our work - both analytic and experimental on the next generation of wide band gap photoconductors using GaN.
