Abstract : Most satellites in existence to date are inherently resonant structures. By a resonant structure is meant that the currents and charges induced on it by an external transient electromagnetic source continue to oscillate without significant damping long after the external source has been turned off. In this note, the emphasis is on how important the resonance effects are on the system-generated electromagnetic pulse (EMP) and how to calculate them. The problem chosen for study is that of a thin cylindrical tube or a wire, which is a resonant structure, excited by a moving charged particle. The natural-mode method in conjunction with asymptotic expansion enables one to get an explicit analytical solution for the induced current on the wire.
