RF Cavity Response: Statistics, Data Acquisition, and Circuit

Contractor will explore techniques for combining EM coupling code and circuit analysis code to detemine transfer functions from fast-pulse HPM threats to circuit-component responses. Techniques must be general enough to consider pulse rise time, total energy, and duration. Treatment must be general neough to work for aircraft, sensor pods, missiles, and satellites. Coupling through antennas, sensors, leaky gaskets, and hatches must be permitted. Contractor proposes to treat the exterior coupling, the RF points of entry, the internal RF response, the internal RF coupling to cables and circuits, and the circuit response as associated, but mostly separate, problems, although the last two aspects probably require simultaneous treatment. Feasibility studies will be made for different approaches to each of these five sub-problems. At present, our inclination is that the external problem may be treated deterministically, but the internal response can only be treated statistically.
