Fast Evaluation of a Filter or Shield Against an Electromagnetic Pulse

Single electromagnetic pulses like lightning, ESD, powerline transients, NEMP, etc., are generally described in time domain, while filters and shields are practically always characterized in frequency domain. This article describes a quick and handy formula and nomogram providing a fair estimate of the filter or shield response to a conducted or radiated threat.

Addressing the Global Threat of EMP Events

Maintaining the resilience of all critical infrastructure segments, including the electric grid, sensitive data centers and vital communication channels, has become a growing concern globally as electromagnetic pulse (EMP) events continue to threaten society and the operation of business and life as we know it.
