Attenuation in continuously loaded coaxial cables

The formula for the attenuation of a coaxial line loaded continuously with magnetic materials involces, after a change of variables, only three parameters, even when the effect of dielectric losses is included. If the dimensions of the line have their optimum values, the, attenuation is a function of only two parameters. The relation is exhibited both graphically and analytically, in forms which can be applied to practical problems. A simple numerical example is given to illustrate the use of the formula.
