As a new kind of sub-wavelength elastic metamaterials, elastic metasurfaces have attracted much attention in recent years since their unique ability in elastic wave modulation. Lately, adaptive elastic metasurfaces make the elastic wave modulation more flexible by introducing new degrees of freedom into the metasurface designs. In this paper, the subunits of the adaptive metasurface are designed by combining the piezoelectric patches with shunted inductance circuit. Due to the tunability of the shunt circuit, the phase shifts for the subunits can be regulated by adjusting the electrical parameters without changing the configuration. According to the generalized Snell’s law (GSL), the designed adaptive elastic metasurface can realize negative refraction with variable deflection angles and plane focusing with variable focal lengths. Besides, the designed metasurface has adjustable operating bandwidth compared with the traditional elastic metasurfaces. Our proposed adaptive elastic metasurface has potential applications in structural damage detection, vibration control and energy harvesting.
