Abstract
A graded leaky coaxial cable comprised of a center conductor, a dielectric surrounding the center conductor, and a braided conductive shield woven around and surrounding the dielectric. The shield has progressively fewer ends along its length, whereby progressively larger non-conducting gaps are formed separated by closely woven groups of carriers, thus facilitating controlled penetration of a radial frequency field through the shield.
