Because the refractive indices of many common polymers are well documented, the Becke line test can be a useful tool in the identification of an unknown polymer. Typical refractive index values of plastics range from 1.35 for PTFE, 1.49 for PP, 1.51 for low-density polyethylene (LDPE), 1.54 ...
In order to provide reliable encapsulants for a high-performance LED, silsesquioxane is one of the most promising materials. However, the refractive indices of conventional silicone materials are relatively low and improvement is necessary. For the aim of developing silicone materials with high ...
To find the refractive index of material X with respect to material Y, we can use the relationship between the refractive indices of the materials with respect to air. 1. Understand the Refractive Index: The refractive inde
Can the effective refractive index of a waveguide be smaller than the smallest value of the refractive indices of materials comprising the waveguide? The author's answer: No, I think that cannot happen. But sorry, I have no proof available. 2021-11-12 Is it correct that the effective refrac...

wavelength and pressure in non-intrusive experiments carried in transparent fluids. It can be used for the identification and characterization of pure materials, for the measurement of concentration of multi-component mixtures etc. In this current scope,refractive indicesof fivebinary mixturesdecane (C10...
As the refractive index of a material increases, the greater the extent to which a light beam is deflected (or refracted) upon entering or leaving the material. The refractive index of a medium is dependent (to some extent) upon the frequency of light passing through, with the highest freque...
The refractive indices of epoxy matrix materials increase monotonically with time during their chemical cure. The measured time dependence can be described by a simple model in which the concentrations of the reacting resin and hardener each decay exponentially in time with their own characteristic ...
