1. A low-loss electrical conductive structure having a length, the conductive structure comprising:
- an innermost conductor shell that extends the length of the conductive structure;
at least two nested concentric conductor shells that extend the length of the conductive structure, each of the at least two nested concentric conductor shells enclosing a preceding conductor shell and having an insulating material therebetween; and
an outermost conductor shell that extends the length of the conductive structure and having an insulating material between itself and the preceding conductor shell.

Abstract
Described herein are improved configurations low loss electrical conductors. The designs for a conductive wire include several mutually insulated coaxial conducting shells. The shells extend through the length of the conductive wire with each successive outer shell completely covering each inner shell. The distribution and size of each may be optimized for frequency, current loads and other parameters to increase the effective cross section of the effective conductor wire. The proposed structures provide for a reduced effective resistance for oscillating currents of frequencies of 1 MHz or more.

13. A high frequency wireless power transfer resonator with low-loss electrical wire suitable for the transmission of high frequency alternating current electrical power having a length and a z-axis, the resonator comprising:
-
a wire having a single innermost conductor shell that extends along the z-axis of the wire, and a plurality of concentric outer conductor shells that extend along the z-axis of the wire, forming successive shells separated by an insulator around the innermost conductor shell, wherein each successive outer conductor shell surrounds and encloses all inner shells; and wherein the wire is shaped to form at least one loop. - View Dependent Claims (14, 15)
