Scanning tip microwave nearhyphen;field microscope

摘要

A nearhyphen;field microscope which operates in the rf/microwave frequency range is described. In this microscope, a scanning tunneling microscope (STM)hyphen;like tip rather than an aperture is used as a pointhyphen;like evanescent field emitter. A spatial resolution of sim;5 mgr;m (sim;lgr;/100thinsp;000) is achieved in the current version. The design of the microscope as well as the principal factors which affect its performance are discussed. copy;1996 American Institute of Physics.
