DOI: 10.1016/j.apsusc.2016.10.146
Abstract: Abstract Methods used to compute the reflection or transmission Mueller matrix of stratified media assume light is a monochromatic plane wave, but measurements with spectroscopic devices invariably involve a finite distribution of wavelengths and incidence… read more here.
