Focuses on a study on which developed an analytic formula for the refractive index of Al[subx]Ga[sub1-x]As semiconductor below the band edge. Composition dependence of the fitting parameters; Analysis of errors; Significance of empirical fit.Deri...
The refractive index of freezing brine is important in order to, for example, estimate oceanic scattering as sea ice develops. Previously, no simple continuous expression was available for estimating the refractive index of brine at subzero temperatures. I show that extrapolation of the empirical fo...
Global Positioning System (GPS). Today, the formulae are important for accurate measurements using radio waves, including GPS and VLBI (Very Long Baseline Interferometry). The new radio wave refractive index formulae of the last decades are ...

It has been shown that mean refractive index can be predicted with possible error of 0–15% depending on the chemical nature of the compound. The majority of oxides show acceptable difference <5% between theoretical and experimental refractive index values and the mean error level for a set of...
object and image distances. The lens maker's formula on the other hand relates the focal length of the lens with the lens material surface curvature of the spherical lens. As the name implies by knowing the lens material (which is indicated by the refractive index of...
The novel IOL power calculation formula for highly myopic eyes demonstrated improved and stable predictive accuracy compared with other artificial intelligence-based formulas.Background Modern cataract surgery has shifted to more of a refractive procedure [1, 2]. Currently, intraocular lens (IOL) power...
