Title:

SUPERCONDUCTING DISK RESONATOR, ITS MANUFACTURING METHOD AND METHOD OF EVALUATING DIELECTRIC ANISOTROPY

Document Type and Number:

Japanese Patent JP2008228156

Kind Code:

A

Abstract:

To provide a superconducting disk resonator that can prevent the occurrence of a notch on a resonance curve and can maintain suitable resonance characteristics even when a substrate with an anisotropic dielectric constant or an anisotropic magnetization rate is used.

The superconducting disk resonator includes a dielectric base substrate (21) having dielectric anisotropy, a disk type resonator pattern (12) that is formed on the dielectric base substrate with superconducting material, and a pair of signal input/output lines (13) arranged on the dielectric base substrate and extending in a straight line towards the disk type resonator pattern. The direction of dielectric anisotropy of the dielectric base substrate is oriented at 90 with respect to an extending direction of the pair of signal input/output lines.
