In situ search for 3D Anderson localization of ultrasound in resonant emulsions
Abstract
After more than a half century of Anderson localization, the subject is more alive than ever" [1]. In acoustics, the first observation of sound localization in three dimensions has been reported in a random elastic network of aluminum beads, a so-called "mesoglass" [2]. Here, we propose to investigate this complex wave phenomenon by studying ultrasonic wave transport through in situ experiments performed within an all-fluid system of disordered resonant scatterers, so-called "resonant emulsions".
