微波光谱是研究金属和超导体在较低频率下电动力学的有力实验工具。为了克服现有低温微波技术的一些缺点，我们使用带状线谐振器作为探针，其中所研究的大块样品代表传输线的一个地平面。我们讨论了由铜和超导铅制成的带状线，并通过测量钽的大块样品的超导转变表明了这种技术的适用性。
Microwave spectroscopy is a powerful experimental tool to study the electrodynamics of metals and superconductors at comparably low frequencies. To overcome some disadvantages of the established cryogenic microwave techniques, we use stripline resonators as a probe where the bulk sample under study represents one of the ground planes of the transmission line. We discuss striplines made of copper as well as superconducting lead, and we show the applicability of this technique with measurements at the superconducting transition of a bulk sample of tantalum.
