Summing the times of propagation for these out and back velocities, we can calculate the total time for a round trip on the parallel arm in the rest frame if the light is passing through a moving refractive medium with an index of refraction

from Cauchy data," Inverse Problems, vol.
Beyond the limitations related to the RTE itself, one can blame the imprecision of several of the input parameters such as the pigments' index of refraction
, their size, and shape distributions or the reflection coefficients at the air/film and film/substrate interfaces.
The square of the index of refraction
with the addition of nonlinear terms becomes
The data taken for the sample outside the IS in the region 300 nm to 800 nm was fitted to the L-M scattering cross section with the parameters: microsphere diameter, real part of the index of refraction
, microsphere concentration, and the instrument acceptance angle.
42) In August 2008, UC Berkeley researchers created a 10-layer fishnet metamaterial structure fabricated on a metal-dielectric stack using focused ion beam milling, achieving a negative index of refraction
for IR wavelengths ranging from 1,475 to 1,775 nanometers (nm).
The index of refraction
is an important physical constant.
Future applications in optical circuit elements and the boosting output power of LEDs are described, and the chapter on the optical properties of ZnO discusses methods for measuring the index of refraction
, among other issues.
Crown glass is harder than flint glass, with a lower index of refraction
and lower dispersion.
Applied physics researchers at the California Institute of Technology, Pasadena, have constructed a nanofabricated photonic material which creates a negative index of refraction
in the blue-green region of the visible spectrum.
The coating has exceptional transparency with a low index of refraction
and virtually no absorption in the visible wavelengths.
Air has a higher index of refraction
for light of short wavelengths, bending rays of blue light more than rays of red light.
