摘要:
A microstrip resonator including a dielectric substrate, a resonance electrode on a first main surface of the dielectric substrate, and a ground electrode over an entire second main surface of the dielectric substrate. The resonance electrode includes a superconducting film and a metal film deposited in that order. The ground electrode includes a superconducting film and a metal film deposited in that order. The superconducting film functions as an electrode in low-temperature operation below a critical temperature, and the metal film functions as an electrode in high-temperature operation at or above the critical temperature. The length of the superconducting film of the resonance electrode is set to be longer than that of the metal film of the resonance electrode, so that the resonance frequency in low-temperature operation is substantially equal to the resonance frequency in high-temperature operation.

Provided is a translucent ceramic which has a high Abbe number, is advantageous in aberration correction, and can be easily produced. The translucent ceramic contains, as a main component, a garnet type compound represented by the General Formula: Y3AlvOw, wherein the condition of 4.4≦v≦5.4 is satisfied and w is a positive number for maintaining electrical neutrality, in which the Al is partially or entirely substituted by Ga and the Y is optionally partly substituted by Gd. The translucent ceramic is suitably used, for example, for lenses arranged with a diaphragm interposed therebetween in a Gauss lens optical system, such as an optical system for single-lens reflex cameras.
