Analysis and Design of Ultra Wide-Band and High-Power Microwave Pulse Interactions With Electronic Circuits and Systems

摘要

This research is directed to understanding and modeling the effects of electromagnetic pulse interactions with electronic circuits and systems, and is focused on four major tasks. (1) Characterization of coupling mechanisms responsible for guiding electromagnetic energy from the source to the electronic components, via topology schemes based on a generalized scattering matrix. Frequency-domain and time-domain solvers are developed for large-scale systems. The results are validated via measurements and via comparison with new canonical solutions to scattering and penetration problems. (2) Characterization of the spurious waveforms at the input ports of the electronic systems. A full-wave three-dimensional analysis of linear passive systems is developed to convert the radiating and conducting EMI into sets of noise sources at the ports of nonlinear active circuits. A network-oriented nonlinear transient simulator is developed for small-signal and large-signal analysis of nonlinear electronics, including the distributed nature of the coupling path and EMI sources. (3) Determination of conditions for induced change-of-logic states and alterations of logic functions for digital circuits and computer systems. A fault-tolerance analysis is developed to determine, classify, monitor and control various system program errors under EM threat. (4) Experiments to validate EM penetration and coupling predictions, and circuit and system fault models.
