| Sumario: | Numerical results for the transient electromagnetic response of a conducting infinite cylinder embedded in a conducting medium excited by an infinite line source are presented. The input current is a Heaviside function of time. The displacement currents are assumed to be negligible in comparison with the conduction currents. The contribution of n=o term (induced line current in the cylinder) is shown to predominate over the higher multipoles. As a rough rule the effect of the outer conductivity must be taken into consideration if it is more tan I0 ̄² times the conductivity of the cylinder. |
