Abstract
A systematic study of surface resistance (R(s)) of YBa2Cu3O7-x ceramic superconductor of different density has been carried out as a functio n of temperature, frequency, rf and dc magnetic fields. The R(s) of th e samples of 50 mm diameter has been measured by cavity end plate repl acement method in the frequency range 10 to 22 GHz using high Q TE01n mode nlambdag/2 long cylindrical resonators. A definite correlation in the value of R(s) as well as its frequency, rf and dc magnetic field dependence with density of the samples has been found.
