Quantitative microwave evanescent microscopy of dielectric thin films using a recursive image charge approach

A recursive image charge approach has been successfully developed for quantitative microwave microscopy of dielectric thin films using the scanning evanescent microwave microscope. With this approach and the recursion-to-circulation algorithm, frequency shift of the microscope as functions of the thickness of the film, dielectric constants of the film and the substrate can be efficiently computed in a circulation way.
