Abstract : A method of constructing ultra-low-loss miniaturized microstrip type microwave transmission lines, circuits, and resonators and their resulting structures are disclosed. The method includes etching a groove of the appropriate width and depth into the surface of a first substrate as determined by a preselected characteristic impedance. Appropriate thin film superconductors are then deposited on the surfaces of the first substrate and a second substrate. The thin film superconductors are then patterned after which the two substrates are sealed together by field-assisted thermal bonding such that a novel two-conductor electromagnetic transmission line results.
