The authors present a brief review of results on the surface impedance of cuprate superconductors, focusing mainly on YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} (YBCO) and evidence of d-wave superconductivity in that material. They then discuss the recent results on BaK-Bi-O thin films, and the effects of DC electric fields on the surface impedance of YBCO films. A summary of their data on high quality thin films and single crystals of the electron-doped Nd{sub 1.85}Ce{sub 0.15}Ce{sub 0.15}CuO{sub 4{minus}{delta}} (NCCO) cuprate superconductor follows. Surprisingly, the measurements on NCCO are consistent with the behavior of an s-wave BCS superconductor, in striking contrast to recent results on YBCO. Finally they discuss some of the interesting potential implications of d-wave superconductivity for microwave applications of the cuprates.
