Abstract

We describe a highly simplified design for a coaxial resonant near field scanning microwave microscope operating at 7.4 GHz configured to measure surface resistance and obtain topographic images with micrometer resolution. This design for a resonant probe tip combined with a highly stable mechanical system developed to rapidly tune the resonant frequency enables a simplified and effective approach to implementing near field microwave microscopy. We present images and measurements performed on a non-uniform granular graphite film sample and the surface resistance results agree with data in the literature.
