Abstract:

Recent developments in electromagnetic EM field sources producing high power microwave HPM or ultra wide-band UWB transient signals have led to a concern about the effects of these environments on modern digital systems. Such excitations, which collectively are referred to as high power electromagnetic HPEM fields, could be inadvertent, like the environment produced by a search radar illuminating a nearby aircraft, or intentional, such as a deliberate attack on a system by an adversary using an electromagnetic weapon. In either case, the effects of these HPEM fields may include system upset, and in some cases, permanent damage. This paper discusses the extension of the Baum-Liu-Tesche BLT equation to include the effects of propagating electromagnetic fields and their coupling to transmission line structures. The usual BLT equation describes the propagation of voltage and current waves along transmission lines. In the extended BLT formalism, both voltage and E-field quantities are treated together and this permits the addition of scatterers and apertures in the models.
