2016 GAO Report on Federal Electromagnetic Preparations

“Key federal agencies have taken various actions to address electromagnetic risks to the electric grid, and some actions align with the recommendations made in 2008 by the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack (EMP Commission). Since 2008, the Department of Homeland Security (DHS), the Department of Energy (DOE), […]

Kinetic Simulations of SPT and HEMP Thrusters Including the Near-Field Plume Region

The particle-in-cell (PIC) method is used to study two different ion thruster concepts-stationary plasma thrusters (SPTs) and high-efficiency multistage plasma thrusters (HEMP-Ts)-in particular, the plasma properties in the discharge chamber due to the different magnetic field configurations. Special attention is paid to the simulation of plasma particle fluxes on the thrusters’ channel surfaces. In both […]

Response of long lines to nuclear high-altitude electromagnetic pulse (HEMP)

During high-altitude nuclear testing in 1962 over Kazakhstan, several system effects were noted due to the high-altitude electromagnetic pulse (HEMP). In particular a 500-km-long aerial communications line experienced a failure due to the damage of its protective devices. This failure is examined in detail beginning with the calculation of the incident HEMP environments, including those […]

Modeling of an EMP conducted environment

The International Electrotechnical Commission (IEC) decided in 1988 to produce a civil standard on the electromagnetic effects of a high altitude EMP (HEMP). Different documents pertaining to the radiated environment and to specifications and test methods have been elaborated and are circulated. A standard conducted environment dependent on many parameters is, however, more difficult to […]
