Optoplasmonic probe to realize scanning near-field Raman microscopy

Scanning near-field optical microscopy.

An average human eye can see details down to 0,07 mm in size. The ability to see smaller details of the matter is correlated with the development of the science and the comprehension of the nature. Today's science needs eyes for the nano-world. Examples are easily found in biology and medical sciences. There is a great need to determine shape, size, chemical composition, molecular structure and...

An overview of scanning near-field optical microscopy in characterization of nano-materials

Scanning Near-Field Optical Microscopy (SNOM) is a member of scanning probe microscopes (SPMs) family which enables nanostructure investigation of the surfaces on a wide range of materials. In fact, SNOM combines the SPM technology to the optical microscopy and in this way provide a powerful tool to study nano-structures with very high spatial resolution. In this paper, a qualified overview of ...

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...
