Specific conductivity of coaxial waveguide

A coaxial waveguide is an electrical cable consisting of a central conductor and a shield arranged coaxially and separated by an insulating material or an air gap. It is used to transmit radio frequency electrical signals. The specific conductivity of a coaxial waveguide depends on the frequency of signal and the specific capacitance of coaxial waveguide, as well as on the tangent of the dielectric loss angle of the insulator material.
