Sub- and supersonic elastic waves in an annular hole phononic metamaterial
Surface acoustic waves are important in a wide range of applications such as telecommunication filters, sensors, and microfluidic devices. Here, patterning of a phononic metamaterial formed of annular hole resonators enables frequency control of the surface wave phase velocities.
