Abstract

Metasurfaces present excellent performance in acoustic wave control with subwavelength thickness, but are typically studied and built for fixed applications. This paper looks at a convenient tunable metasurface design with Helmholtz resonance. Moving sliders in the design allow full phase shift with a high transmission ratio in a broad frequency bandwidth. The design can be used for tunable wave front redirection, focusing with varying wavelengths and sound source illusion, as are shown in numerical and experimental examples. This design could be a superb option when there is a need for tunable acoustic wave modulation.
