We present results on the temperature dependence of the surface impedance of high-quality thin films and single crystals of the electron-doped Nd[sub 1.85]Ce[sub 0.15]CuO[sub 4[minus][delta]] cuprate superconductor. Surprisingly, these measurements are consistent with the behavior of an s-wave BCS superconductor. We also briefly review some highlights of surface impedance measurements on hole-doped cuprate superconductors, and contrast those with the results on Nd[sub 1.85]Ce[sub 0.15]CuO[sub 4[minus][delta]]. 31 refs., 3 figs., 1 tab.
