A method includes: providing an element having mutually exclusive first and second portions with an initial index of refraction; and applying energy to the first portion in a manner causing the index of refraction thereof to change by at least 0.05 in relation to the index of refraction of the...

The ratio of the speed of light in a vacuum to that in a given material is known as its index of refraction, n. The index of refraction of a material is usually a function of the wavelength of light. Values in the literature for various materials correspond to n determined with the ...

The ratio of the speed of light in a vacuum to the speed of light in a medium under consideration. Also calledrefractive index. American Heritage® Dictionary of the English Language, Fifth...
Experimental verification of negative index of refraction We present experimental scattering data at microwave frequencies on a structured metamaterial that exhibits a frequency band where the effective index of refraction ( n ) is negative. The material consists of a two-dimensional array of r... RA...
Several methods exist to accurately measure the index of refraction. Here are some widely used techniques: Using refractometers: Refractometers are optical devices that determine the index of refraction by measuring the angle at which a light ray bends when passing through a sample material. ...
Furthermore, we compute the in-plane propagation loss of the material according to the retrieved effective index of refraction via $$\begin{array}{*{20}{c}} {L\left[ {\frac{{{\mathrm{dB}}}{{\mathrm{m}}} \right] = \frac{{\omega {\mathrm{Im}}\left( {n_{{\mathrm{eff}}} \...
(General Physics)physicsa measure of the extent to which radiation is refracted on passing through the interface between two media. It is the ratio of the sine of the angle of incidence to the sine of the angle of refraction, which can be shown to be equal to the ratio of the phase sp...
The invented method of permanent increase of index of refraction to required value in polymeric materials intended particularly for the preparation of planar optical waveguides, interference layers for optical filters or mirrors is characterized in that polar material based on polymers is treated in a ...
