Thin film superconducting LC network

A high-Q lumped LC network comprising

• (a) a first dielectric substrate having first and second oppositely-disposed surfaces and having a first dielectric constant,
• (b) at least a first thin-film superconducting conductor disposed on one of said first and second surfaces defining an inductor having a plurality of closely-spaced adjacent turns,
• (c) at least second and third thin-film superconducting conductors disposed on said first and second surfaces, respectively, said second and third conductors opposing each other and having at least a portion of the dielectric substrate therebetween to realize a capacitor, and
• (d) thin-film superconducting conductor means for interconnecting the first conductor and a preselected one of the second and third conductors, thereby interconnecting the inductor and the capacitor to realize a desired LC network,
• (e) a channel within the substrate disposed between the adjacent turns of the inductor.
