Corrugated coaxial cable with high velocity of propagation
First Claim
1. A coaxial cable comprisingan inner conductor, a foamed polymeric dielectric surrounding said inner conductor and having a density below 0.17 g/cm3, and a corrugated outer conductor surrounding said dielectric and dimensioned to create a ratio of the actual length of said outer conductor to its linear length such that the cable has a velocity of propagation greater than 90% of the speed of light, the corrugations in said outer conductor forming troughs and crests with the troughs engaging said dielectric.

Abstract
A corrugated coaxial cable including a core with at least one inner conductor and a highly expanded polymeric foam dielectric surrounding the inner conductor. This coaxial cable has a corrugated outer conductor closely encapsulating the foam dielectric. The corrugated coax cable is dimensioned to provide the cable with a velocity of propagation of greater than 90% of the speed of light.
