Refractive-index measurement of absorbing condensed media

Refractive-index measurement of absorbing condensed media.

Measurement of the refractive index of highly turbid media.

We demonstrate a first simultaneous measurement of the real and imaginary parts of the refractive index of a highly turbid medium by observing the real-time reflectance profile of a divergent laser beam made incident on the surface of the turbid medium. We find that the reflectance data are well described by Fresnel theory that correctly includes the effect on total internal reflection of angle...

Measurement of refractive index of PF-5060

For optical studies of boiling heat transfer process, it is essential that the refractive index and its dependence on temperature for the test liquid be known. In this work a simple set-up was built to measure the refractive index of Fluorinert Liquid PF-5060 with temperature compensation and temperature control. The pinhole laser light beam was used for determining the refraction angle. The re...

Broadband, Volumetric Negative-Refractive-Index Media

Broadband, Volumetric Negative-Refractive-Index Media by Scott M. Rudolph Chair: Anthony Grbic Since their invention, negative-refractive-index (NRI) media have been plagued by three primary limitations: narrow bandwidth, high loss and polarization dependence. In this thesis, each of these problems is addressed. First, a new metamaterial topology that achieves negative permeability over a broad...

Gas analysis by refractive index measurement.

A B C light in a medium is difficult, it is quite easy to compare the velocity of light in one medium with the velocity of light in another. A suitable instrument for this purpose is the Rayleigh Interference Refractometer. This instrument is shown diagramatically in figures 1 and 2. Figure 1 is a plan view showing the components as they appear from above. Figure 2 is a side view of the same ar...
