Effects of Backscattered Electrons on SGEMP Response

Perturbations introduced into the system-generated electromagnetic pulse (SGEMP) response arising from backscattered electrons are explored. Both the external response of a cylinder and the internal response of a cavity are treated. Perturbations in peak response are found to be as much as a factor of three at certain points on the structures, while perturbations up to 20% are found in the peak response at points on the structure where the response is maximum.
