Abstract

It is shown that energy flow between weakly coupled reverberant systems, for example reverberation rooms coupled by a small window, can be Anderson localized. The effect is significant when the energy flow rate (in units of inverse time) is comparable to or less than modal spacings. It is found that the energy partition in the localized regime slightly overshoots its (low) asymptotic value. The effect is demonstrated in numerical simulations and in a laboratory ultrasonic system.
