Abstract
We present an exact analysis for the electromagnetic coupling to a thi n overhead cable from a vertical line current source terminated in a p erfectly conducting ground plane. The spectral method employed permits a full satisfaction of the impedance boundary condition at the cable. The quasi-static limit of the obtained solution in the time domain, f or the net cable current, is expressed in closed form. The results are relevant to the induced currents on power and communication lines.
