The HEMP (High-altitude Electromagnetic Pulse) response of a long transmission line buried in the earth
Abstract
This paper documents the calculation of the current coupled to a long, buried, insulated cable excited by a horizontally polarized plane-wave electromagnetic pulse (EMP) field. This result is compared to the current measured on a similar long, buried cable located approximately 800 ft from a radiating, horizontally polarized EMP simulator having the same driving horizontal field. Originator-assigned key words include: Transmitted E field below ground, Conductivity, Dielectric constant, Distributed source, and Matrix tridiagonalization.
