Lumped-element modeling of satellite SGEMP excitation

A technique utilizing a lumped-element approach has been developed for modeling the SGEMP response of a satellite-like structure. The space outside the structure is modeled by a number of current generators representing the real current produced by emitted electron charge, and capacitors are used to model the displacement current. Numerical solutions are obtained for a single electron moving away from a sphere, and compared with more exact solutions utilizing the Maxwell equations directly.
