Summary:
This paper describes a model of current propagation on single conductor line which does not have explicit return path. As a fundamental element, we use the current on a finite length straight line and we derive the electric field caused by the current. Using models consists of the fundamental element, we obtain an integral equation in the complex frequency domain based on the boundary conditions on the conductor surface. The time domain current and charge waveforms are obtained by the numerical Laplace transform. The method figures out the source of electric field on the conductor surface and makes clear the mechanism of the current propagation based on the recursive induction of the current. First, we apply the proposed method to a uniform cylindrical single conductor line and clarify the mechanism of current propagation without explicit return path. Next, we analyze the case that the radius of single conductor line changes at a point and confirm the reflection and transmission phenomena. The mechanism of these phenomena is revealed by the charge distribution.
