WebNov 24, 2024 · The refractive index can be measured with a relative uncertainty close to $$10^{-3}$$ over a wide range of wavelengths, as needed for a growing number of optical applications. ... where \(\nu\) is a wavenumber, n is the refractive index and k is the extinction coefficient. n and k characterize the real and imaginary parts of the complex ... WebMay 7, 2024 · All electromagnetic waves experience some reflection when they reach the interface between two media that have refractive index contrast. The reflection of a plane wave can be perfectly described using a reflection coefficient, but this is not the whole story in a complex structure like a printed circuit board.
