EMP energy transfer function on EED

The hazards of electromagnetic radiation to ordnance (HERO) program has extensively tested the detonating device, called electro-explosive device (EED), which heats up and initiates detonation via current flow. EED accidents can occur due to the action of an electromagnetic pulse (EMP). Any kind of system can be considered as an antenna to receive EMP energy and this energy may couple to the EED. The EED and its related problems are introduced and heat flow equations are studied. The amount and type of current induced in wires to an EED depends on the type of receiving antenna. Three basic types of antenna are discussed, loop antenna, dipole antenna and top-loaded antenna.
