EMP and HPM Suppression Techniques
Abstract
Micron sized metal particles embedded in an insulative binder exhibit varistor action. It is believed the dominant conduction mechanism in successful devices is inter-metallic quantum tunneling. In this report, the quantum tunneling aspects are thoroughly investigated. Computer models are developed based on the quantum analyses along with the introduction of chaos theory. The computer models are presently limited to two dimensions, so predictions are basically qualitative. However, the qualitative results are observed empirically. The computer models and the empirical results indicate there are one or more conduction mechanisms in addition to quantum tunneling. Devices were constructed and tested according to ESD specifications. For two classes, the failure rate was zero. Some leading edge overshoot was observed, but it is believed this is mainly an artefact of the test system configuration.
