Anderson localization of ultrasound in plates: further experimental results.
Diffuse wave transport is studied in a thick plate with densely machined-in multiple scatterers. As anticipated by theory, energy at short wavelengths diffuses across the structure. Energy localizes at longer wavelengths for which lambda2pi is comparable to the mean free path.
