This report describes the presently available state-of-the-art analysis tools and extensions of these that are applicable to enhancing our understanding of the interaction and coupling phenomena associated with the high-altitude nuclear electromagnetic pulse (HEMP) and its effects on military systems. Such an in-depth understanding would provide the framework for a more scientific approach to system testing and hardening. In the report, we also briefly review past research programs in this area and evaluate the degree of their success. The emphasis in system assessment tools is placed on a probabilistic failure analysis approach that can provide a framework for vulnerabilities assessment and hardening. In coupling the emphasis is placed on a phenomenological understanding which involves a multifaceted approach involving analytical, computational, and experimental techniques in a complementary way. In component susceptibility, the emphasis is on the development of validated one, two and possibly three dimensional computer models that include the major physical phenomena such as heat and electronic transport equations. A gap exists in being able to express physics quantities in these codes in terms of nonlinear circuit parameters that can be used in the circuit codes.
