Abstract

In a typical optical experiment monochromatic electromagnetic radiation, ranging from the infrared (IR) to the ultraviolet (UV), is shone onto a specimen surface. The amount of reflected, transmitted or absorbed intensity as a function of frequency can be detected as well as the change of polarization state. From this kind of information the absorbed energy at frequency ω per volume and time, W(ω), can be deduced. Classical electrodynamics gives for this quantity:
$$ W(omega) = \frac{{\omega{\varepsilon_2}(\omega)}}{{4\pi}}<{E^2}>\;=\sigma(\omega)<{E^2}>$$
