Query: Surface-resistance measurements using superconducting stripline
  resonators   We present a method to measure the absolute surface resistance of conductive
samples at a set of GHz frequencies with superconducting lead stripline
resonators at temperatures 1- 6K. The stripline structure can easily be applied
for bulk samples and allows direct calculation of the surface resistance
without the requirement of additional calibration measurements or sample
reference points. We further describe a correction method to reduce
experimental background on high-Q resonance modes by exploiting TEM-properties
of the external cabling. We then show applications of this method to the
reference materials gold, tantalum, and tin, which include the anomalous skin
effect and conventional superconductivity. Furthermore, we extract the complex
optical conductivity for an all-lead stripline resonator to find a coherence
peak and the superconducting gap of lead.
