<p>A superconductive transmission line (20) is formed of mixed metallic oxide ceramic material, particularly Y1Ba2Cu3O7-x drawn epitaxially upon a substrate (76). The superconductive material has basal crystallographic planes (44) in alignment with copper oxide of the ceramic material. The planes (44) are parallel to the substrate (72). The transmission line (20) is constructed of a plurality of electrically conductive elements (38, 40, 56, 60), each of which is formed of the superconductive material. The conductive elements (38, 40, 56, 60) are arranged with the basal crystalline planes (44) parallel to an axis (46, 72) of the transmission line, along which axis power is to flow. Thereby, magnetic fields (48) induced by currents flowing in the conductive elements (38, 40, 56, 60) intersect the conductive elements (38, 40, 56, 60) perpendicularly to the basal crystallographic planes (44) to maximize the current which can flow while retaining linearity between magnetization and applied magnetic field. Thereby, alternating current can be transmitted by the transmission line without the introduction of hysteresis losses which would develop heat and quench the superconducting characteristic of the transmission line (20). <IMAGE></p> |
