Refractive index and temperature coefficient of refractive index of Al2O3- and SiO2-water nanofluids

open access: yesInternational Journal of Thermofluids, 2022
Measurements are made of the refractive index and temperature coefficient of refractive index (∂n/∂T) for two nanofluids, Al2O3-water and SiO2-water, over the temperature range 20–40°C at a wavelength of 632.8 nm.

Liquid core photonic quasi-crystal fiber plasmonic refractive index sensor for wide refractive index detection range

open access: yesAdvanced Electromagnetics, 2022
In this paper, a photonic quasi-crystal fiber plasmonic refractive index sensor is numerically analyzed. The fiber core is infiltrated with six hypothetical liquids, which refractive indices of them vary from 1.44 to 1.49. The reason for filling the core

Refractive index of rubber [PDF]

open access: yesJournal of Research of the National Bureau of Standards, 1935
Abstract This paper presents an exploratory study of the refractive index of rubber. Previous observations on the refractive index of rubber have been, for the most part, restricted to transparent samples. In the present investigation, however, by using reflected light rather than light at grazing incidence, it was found possible to extend the ...
