Abstract :
This paper presents, for the first time, the frequency-domain theory of magnetic transmission lines, i.e., transmission lines where electromagnetic energy guidance is assured by means of two magnetic-flux carrying parallel magnetic wires, as opposed to the ordinary situation of two current carrying parallel electric wires (an electric transmission line). Propagation equations for the fundamental quasi-TEM mode are established and solved. Wave parameters are analyzed. A transmission matrix is described.
