Abstract
Stabilization of dielectrics used in transmission lines is described. In one implementation, the transmission line includes an outer conductor, a center conductor, and a dielectric material. The dielectric material separates the outer conductor from the center conductor. The center conductor has a conductive surface with a pattern distributed thereon. The pattern is configured to prevent the dielectric material from moving when the transmission line is exposed to an extreme temperature fluctuation. The pattern increases a coefficient of friction between the center conductor and dielectric material sufficient enough to prevent undesired motion of the dielectric material. In one implementation, the pattern includes indentations that are generally, but not necessarily limited to between 0.001 and 0.004 of an inch deep.
