2. Overview of HPM Effects Research
Power Supply
Power Bus
EMI Gasket
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 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
Comparison of results from experiments and simulations
HPM Effects Circuit Model
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).
