Attenuation in Continuously Loaded Coaxial Cables

Abstract

The formula for the attenuation of a coaxial line loaded continuously with magnetic materials involves, 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.

“…Analytically, however, for the conditions 0<<1, CZoco/2 = 1.05(ia)2Ert(l/h)210-20 (16) <<1, we note that the amplitude distortion of the periodic structure is a combination of that due to the 1.0 skin effect and one defined by cadB = 86.8(CZo)2f2/(s + b) (19) which follows directly from (11), if we know that the v70 6 < length unit in the repeated structure is (s+b). As forward propagation of a pulse train into the matrix is an operational demand, it is clear that 0/c> CZ0 For other conductor materials this response parameter is a desirable condition (see Section V-D).…”

“…The analysis of the attenuation in coaxial pulse generator launching effective step functions into the matrix. (This demands a rise time much less than systems has already been reported [19] and it is suf-10-11 sec for the design considered here.) It is therefore ficient in the present case to draw attention to such more to the point to assume the feasibility of a genera-theoretical work.…”
