Abstract
We describe the near-field scanning microwave mi-
croscopy of microwave devices on a length scale much
smaller than the wavelength used for imaging. Our mi-
croscopecan be operated in two possible configurations,
allowing a quantitative study of either material proper-
ties or local electric fields.
Introduction
In recent years, several novel methods of scanning
probe microscopy have been developed. Generally spea-
king one can divide these methods into two main ap-
proaches, driven by distinct motivations. In the first
approach the main goal is to study material properties,
