Studies of High-T sub c Superconducting Films for High-Power Microwave Applications

Abstract

During the period of this grant, October 15, 1997-April 14, 2001, characterization has been carried out in order to understand microwave properties of grain boundaries. Measurements in an externally applied dc magnetic field in addition to the rf field of the stripline resonator. Intermodulation distortion measurements have also been carried out as a function of the grain boundary angle. The measurements in external magnetic fields require the use of a suspended micros trip geometry without superconductivity ground planes so that the shielding effects of the ground planes could be avoided. The film parameters which give the best device characterization have been established.
