摘要

Metasurfaces with sub-wavelength thickness and planar profile have exhibited novel waves manipulating properties that could not be realized by traditional materials. Here we present an acoustic metasurface (AMS) model composed of double-split hollow sphere (DSHS) resonator arrays with the functionality of modulating reflected wavefronts at will. By tailoring the split-hole diameter of DSHS, the AMS can be designed to cover 2π phase shifts with the step of π/4. The acoustic wave perpendicularly and obliquely incident on the AMS can be reflected at any angle. These anomalous manipulations of the reflected wave's direction are simulated to fulfill the generalized Snell's Law by projecting suitable phase gradient. Such AMS provide another path to acoustic application such as acoustic imaging, cloaking, beams steering devices.
