Abstract

The effect of the patterning process on the nonlinearity of the microwave surface resistance R$ of YBCO thin films is investigated in this paper. With the use of a sapphire dielectric resonator and a stripline resonator, the microwave R§ of YBCO thin films was measured before and after the patterning process, as a function of temperature and the RF peak magnetic field in the film. The microwave loss was also modeled, assuming a Jrf dependence of Zs(Jrf) on current density Jrf. Experimental and modeled results show that the patterning has no observable effect on the microwave residual RS or on the power dependence of R$.
