Abstract: Controlling the directionality of acoustic scattering with single acoustic meta-atoms has a key importance for reaching spatial sound routing with acoustic metamaterials. In this paper, we present the experimental demonstration of the acoustic analogue of the Kerker effect realized in a two-dimensional coiled-space meta-atom. By engineering the interference between monopolar and dipolar resonances within a meta-atom with a high effective refractive index, we achieve directional scattering with suppressed backward or forward response at the first and second Kerker conditions, respectively. Experimental measurements of the scattered pressure field, in a parallel-plate waveguide environment, show good agreement with the full-wave simulations. Our results validate the feasibility of Kerker-inspired wave control in acoustic systems and open new opportunities for directional sound manipulation. [ABSTRACT FROM AUTHOR]
