Scanning Near-Field Millimeter-Wave Microscope.

Millimeter-wave scanning near-field microscope using a resonant waveguide probe

We demonstrate a millimeter-wave surface imaging technique using a near-field scanning millimeter-wave microscope with a resonant standard waveguide probe. The metallic probe tip in the resonant waveguide was designed to couple energy into and out of the resonant waveguide. By measuring the shift of the resonant frequency and the change of the quality factor in the near-field zone, we obtained ...

Scanning Near-Field Millimeter-Wave Microscopy Using a Metal Slit as a Scanning Probe

In this paper, a novel type of scanning near-field millimeter-wave microscopy using a metal slit-type probe is proposed. A tapered reduced-height rectangular waveguide forms the slit aperture, which has a width much smaller than one wavelength and length of the order of . The slit probe can be operated in theTE10 mode and, thus, results in high transmission efficiency, even when the width is ex...

Near-field scanning optical microscope probe analysis.

In this article results of a comparison of two NSOM probe characterization methods are presented. Scanning electron microscopy analysis combined with electromagnetic field modeling using the finite difference in time domain method are compared with measured far-field radiation diagrams of NSOM probes. It is shown that measurement of far-field radiation diagrams can be an efficient tool for dail...
