Noting that sin 90° 1, Snell’s law in this case becomes. In general, an index of refraction is a complex number with both a real and imaginary part, where the latter indicates the strength of absorption loss at a particular wavelength-thus, the imaginary part is sometimes called the extinction coefficient k " (PDF). Ni-rich NMC (LiNi x Mn y Co z O 2 x + y + z 1, x 0.6) with high capacity (>200 mAh g 1) has demonstrated great potential as a cathode material for high energy density LIBs 1,2,3. The cathode particles were assumed to have a refractive index of 2.19 (refractive index of NiO as specified by the supplier), and 1. When the incident angle equals the critical angle ( 1 c ), the angle of refraction is 90° ( 2 90°). Thus, it is especially important to cite the source for an index measurement if precision is required. There are also weaker dependencies on temperature, pressure/ stress, etc., as well on precise material compositions (presence of dopants, etc.) for many materials and typical conditions, however, these variations are at the percent level or less. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength (λ) of 589 nanometers. The thickness and the refractive index for each required film, are obtained. Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion.
