Emp And Geomagnetic Storm Protection Of Critical Infrastructure, George H. Baker Iii
Emp And Geomagnetic Storm Protection Of Critical Infrastructure, George H. Baker Iii
George H Baker
EMP and solar storm wide geographic coverage and ubiquitous system effects beg the question of “Where to begin?” with protection efforts. Thus, in addressing these “wide area electromagnetic (EM) effects,” we must be clever in deciding where to invest limited resources. Based on simple risk analysis, the electric power and communication infrastructures emerge as the highest priority for EM protection. Programs focused on these highest risk infrastructures will go a long way in lessoning societal impact. Given the national scope of the effects, such programs must be coordinated at the national level but implemented at local level. Because wide-area EM …

Risk-Based Critical Infrastructure Priorities For Emp And Solar Storms, George H. Baker Iii

Two electromagnetic phenomena have the potential to create continental-scale disasters. The first, nuclear electromagnetic pulse (EMP), results from a nuclear detonation high above the tropopause. The second, a major solar storm, or "solar tsunami" occurs naturally when an intense wave of charged particles from the sun perturbs the earth's magnetic field. Both phenomena can debilitate electrical and electronic systems necessary for the operation of infrastructure systems and services. One reason why a U.S. protection program has yet to be initiated is that policy makers continue to wrestle with the question of where to begin, given the Department of Homeland Security’s …

Emp: A Brief Tutorial, George H. Baker Iii

A nuclear detonation at altitudes from about 30 to 500 kilometers generates a strong electromagnetic pulse (EMP) that propagates to points on the ground within the line-of-sight of the burst. For bursts above 100 kilometers, electronics can be affected over continental scale areas. The EMP induces large voltages and currents in antennas and cables of electronic systems that will upset operation or damage circuit components if protection measures are not present. The article provides a brief tutorial on EMP environments, effects and protection.

A Unified Topological Approach To Electromagnetic Environmental Effects Protection, George H. Baker, J. Philip Castillo, Edward F. Vance

The presentation recommends an approach for unifying electronic system protection designs for a wide spectrum of electromagnetic environments. A general electromagnetic topological construct is developed as the basis for a consistent shielding and terminal protection methodology. Spectral characteristics of multiple interfering electromagnetic sources, both internal and external, are described. Effects addressed include EMI/EMC, lightning, nuclear EMP, and RF weapons. Protection practices for individual effects are discussed and means for integrating these into a single protection topology.
