Superconducting multilayer electrode and method of producing same

摘要

A superconductor layer (5) is formed on one side of a dielectric substrate (10), and with this superconductor layer (5) as a conductor layer of the bottommost layer, superconductor layers (1 to 4) and dielectric layers (30-1 to 30-4) are alternately laminated with each other. Thus, a superconducting multilayer electrode is provided which is laminated with at least one TEM mode transmission line (LN1 to LN4) which is constituted of a pair of superconductor layers (1 to 5) with a dielectric layer (30-1 to 30-4) sandwiched in between, and the superconductor layer and the dielectric layer have film thicknesses which are set so that the maximum value of the current density flowing through each superconductor layer becomes the same. The resistance to electric power of the superconducting multilayer electrode is proportional to the number of laminated layers. <IMAGE>
