  2. Overview of HPM Effects Research Power Supply EMI Gasket Power Bus Mapping of Electromagnetic Fields Nonlinear Circuit Dynamics • HPM Effects Involve: • Complex field distributions that are very sensitive to changes in the system • Circuit response that is very sensitive to the HPM waveform characteristics (amplitude, frequency, pulse length, modulation bandwidth, etc.) • Critical scaling laws as IC technology advances

  3. HPM Effects Spectrum HPM • Electronic systems may be susceptible to HPM anywhere across the 200-5000 MHz frequency band. • Achieving high probability of effect requires wideband sources capable of: • 10 MW powers and kJ pulse energies for close range applications (e.g. vehicle stopping & IED defeat) • 100 MW powers for long ranges (e.g. missile defense).

  4. Previous HPM Effects Studies • We have made great strides in understanding the basic electronics of HPM upset in circuits. • Our new models yield fast, accurate predictions using commercial circuit simulators (e. g. ADS). Comparison of results from experiments and simulations HPM Effects Circuit Model
