Abstract

The electromagnetic properties of a superconducting dielectric resonator (SDR) at W-band are described. The resonator consists of a cylindrical dielectric tube with two end plates of YBa/sub 2/Cu/sub 3/O/sub 7/ (with T/sub c/>or approximately=80 K) mounted inside of a Cu cavity. The resonator has a Q-factor in excess of 10/sup 5/ to 10/sup 6/ at cryogenic temperatures when constructed using a sapphire tube. The SDR is physically small, compact, rigid, lightweight, and easy to manufacture.<>
