Abstract

Using a free electron laser we have performed midinfrared transmissionand reflection measurements in strongly scattering Ge powder. We havestudied the wavelength dependence of the scattering properties and theoptical absorption. Results indicate that our samples are close (kls≃3)to the Anderson localization transition but still above it. This is incontrast to the recently reported strong localization of light (kls<1)in a similar powder of lower refractive index particles (GaAs).
