Summary

We performed research in the field of electromagnetic wave chaos and High Power Microwave (HPM) effects in electronic systems. Our emphasis was on issues likely to be most relevant to the coupling of electromagnetic radiation into systems and its effects on systems, as in electromagnetic attacks of military electronics.. Our program addressed the following issues of relevance to the understanding of HPM effects on electronic systems: • The extension of the previously developed Random Coupling Model statistical description of wave coupling into enclosures to describe a) the coupling through apertures, b) the coupling to mixed systems for which only part of the ray phase space is chaotic, and c) the coupling to systems of systems in which the components have varying degrees of isolation, for example chains of cavities. • The further development of time domain models for the response of systems excited by pulses of wave energy, including nonlinear effects • The Extension of HPM upset experimentation and modeling to complex networks of interconnected circuits. Our aim is to develop a generalized approach for modeling HP
