Which range of electromagnetic spectrum is better for observation of Anderson Localization?

14 July 2016 1 4K Report

Hi every one.

Why observation of anderson localization, in the visible and infrared spectrum is difficult, whereas in the terahertz (due to higher dielectric contrast) it can be observe easily?

please, could somebody explain?

Thank you

Malcolm White

It is because the wavelength is longer, so that the scattering length is less than a wavelength. The article below explains it well.
