Hi
https://en.wikipedia.org/wiki/Mathematical_descriptions_of_opacity
it is mentioned above that "in non attenuating media, the refractive index and angular wavenumber are related by:
A complex refractive index can therefore be defined in terms of the complex angular wavenumber defined above:
where n is the refractive index of the medium."
Is it right to say that some mediums are attenuating and some non attenuating? and we use
for non attenuating mediums and
for attenuating mediums?
or non attenuating situations is just an approximation and all media are attenuating?
