Abstract : The following phases were targeted for this project: (1) calculation and numerical simulation of a Josephson-inductance tuned HTS ring-resonator and an array for negative index material applications, (2) fabrication of single resonator structures with integrated Josephson tuning and control lines; measurement of the basic features of such resonators, (3) measurement of microwave properties of a single resonator, such as quality factor, tuning range, microwave field-strength distortion and qualityfactor dependence on tuning. Feedback for changes in design and fabrication, (4) design and fabrication of arrays of tunable resonators, and (5) testing for microwave properties and negative index operation. The report continues with a section on the results obtained in the manufacturing of passive high Tc SSRRs, followed by a section about the properties of the realized SRRs and finally by describing how to ad Josephson junction devices in the resonator structure for the purpose of tuning. The specific challenges in this regard are also mentioned.
