Absorbance dielectric function

Description

This node allows defining any dielectric function for describing homogenous isotropic materials ranging from dielectrics (water, glass, …) to semiconductors and metals. This is defined as « Absorbance », with refractive index (real part) and absorbance spectrum.

Children nodes

n	Refractive index spectrum (real part), unit-less
a	Absorbance spectrum, m-1 unit.
