Abstract

Theoretical deviation shows that a superconductor surface has (1) a total reflection for EM radiation, and (2) an evanescence layer without loss. Both properties are promising for waveguiding high density of radiation flux. High T_c superconductor materials have demonstrated diminishing absorption in the far infrared¹ and in the millimeter wave² experiments. Methods for constructing and testing the superconductor-coated waveguides are proposed. It is believed that for both data and power transmission, waveguiding in a superconducting conduit offers a safe, secure, and EM-interference-free method over a single core wire and deserves our attention.
