Strip-shaped samples in a microwave Corbino spectrometer.
The Corbino geometry, where a flat sample is pressed against an open end of a coaxial cable, is an established probe layout for broadband microwave spectroscopy. Here we show that besides the conventional case of the sample covering the complete Corbino probe, also strip-shaped samples can be studied with a Corbino spectrometer. This increases the sensitivity for highly conductive samples and furthermore opens the route for the study of anisotropic materials.
