Experimental measurements of perfect absorption on surface water waves

Abstract : We present experimental measurements of perfect wave absorption on surface gravity-capillary waves. The equilibrium between friction losses and coupled resonance yields a zero reflection coefficient. As a simple resonator, among other possibilities, the trapped modes produced by a non-symmetrical cylinder are used to generate absorption.
