The guided and radiated energy in wire transmission

THE object of this paper is to give a brief preliminary account, without mathematical details, of the results of a mathematical investigation of wave propagation along wires. This investigation had its inception in the problem of radiation from transmission lines, which was discussed by the writer some time ago.1 It was found that, in order to completely and directly account for radiation phenomena, it was necessary to recognize the incomplete and approximate character of the usual engineering transmission theory, discard the special assumptions underlying it, and develop the theory ab initio from Maxwell's equations. Theoretically interesting and instructive deductions followed from this study, which are believed to justify the present preliminary discussion, which the writer hopes to supplement with a paper dealing with the mathematical theory.
