Abstract
A coaxial cable, including an inner conductor and an outer conductor surrounding the inner conductor and a thermally responsive material positioned between the outer conductor and the inner conductor. The outer conductor is in a generally concentric relationship to the inner conductor and the inner and outer conductors are adapted to connect to an energy source. A thermal change in the thermally responsive material alters the generally concentric relationship between the outer conductor and the inner conductor.
Claims12
A coaxial cable, comprising:
- an inner conductor;
- an outer conductor surrounding the inner conductor, the inner conductor in general concentric alignment with the outer conductor, the inner and outer conductors adapted to each connect to an energy source;
- and
- a thermally responsive material disposed between the inner and outer conductors;
- wherein a change in temperature of the thermally responsive material alters the concentric alignment of the inner and outer conductors.

A coaxial cable, comprising:
- an inner conductor;
- and
- an outer conductor surrounding the inner conductor, the inner conductor in general concentric alignment with the outer conductor, the inner and outer conductors each adapted to connect to an energy source, wherein the impedance of the coaxial cable is related to the eccentricity of the inner conductor relative to the outer conductor which is responsive to a change in temperature.
A coaxial cable, comprising:
- an inner conductor;
- an outer conductor surrounding the inner conductor, the inner and outer conductors each adapted to connect to an energy source;
- a dielectric material disposed between the inner and outer conductors;
- and
- a mechanism coupled to the dielectric material configured to regulate the dielectric material to position the inner conductor relative to the outer conductor.
