From these parameters, the equivalent refractive index of the lens was calculated.

We demonstrate a fiber in-line Fabry-Perot interferometer cavity sensor for refractive index measurement.

An interestingly simple low-dispersion cloak is also suggested for background materials with larger refractive index.

The equivalent refractive index and the power of the lens were calculated from these parameters.

It was observed that the modified refractive index induced a wavelength shift in the FPI.

The refractive index of blood is a key biophysical parameter, which can reflect the physiological state.

Main outcome measures: The thickness, anterior and posterior radii, equivalent refractive index, and power of the lens.

The effects so produced are the differential results of the change of figure and of refractive index.

Also, we quantified the sensitivity of MC-NPA chip to changes in bulk refractive index (RI).

We report the experimental demonstration of a broadband negative refractive index obtained in a labyrinthine acoustic metamaterial structure.

Where the surface was hard and dense, Brewster found the refractive index to approach that of semi opal.

It has practically the same refractive index as air, therefore it is, to all intents and purposes, invisible.

The Luneburg lens is a spherically symmetrical gradient refractive index (GRIN) device with unique imaging properties.

Overall, the optimization approach was able to improve the refractive index but at the cost of increased frequency dependence.

Material and methods: A custom complete-arch model was fabricated with a refractive index similar to that of tooth structure.

Using different theoretical models, we employ multiphoton absorption rates to compute the nonlinear refractive index by a Kramers-Kronig transform.
