The Present Status of Wire Transmission Theory and Some of its Outstanding Problems

The rapid development in the technique of wire transmission and the increasing complexity of the problems involved calls for a more adequate theoretical guide and a more rigorous transmission theory. This paper gives an account, practically without mathematics, of classical transmission theory and its limitations; of the several ways the problem may be attacked more fundamentally and rigorously, and the lines along which transmission theory must be extended, as the writer has come to view the problem in the light of his own experience.
