Generalised theory of uniform transmission lines

The conventional circuit theory of uniform two-conductor transmission lines (TEM mode) assumes that at any cross-section the current in one conductor is equal and opposite to that in the other. This is not necessarily true, and even when it is true the resulting theory does not permit solution of some simple problems such as evaluation of the voltage difference between two points on the same conductor. The author presents a more general circuit theory which does permit solution of such problems and does not demand current balance. He shows that when there is current imbalance the expressions for voltage contain a term which depends linearly upon line length, as well as the familiar hyperbolic function terms
