The instrumentation combines a vector network analyzer, an interferometry-based matching network and an evanescent microwave coaxial probe. The measurement sensitivity of the measured microwave signals can be enhanced at the desired frequency in the range 1-26 GHz. Other advantages such as simplicity of operation and high spatial resolution are also achieved. As a demonstration, we have observed a high electromagnetic coupling between the probe tip and liquid droplets featuring emergent applications in biological and chemical researches.
