Sparse acoustic reflector
A broadband sparse acoustic reflector includes a periodic array of laterally spaced apart unit cells, each unit cell having a plurality of longitudinally positioned Helmholtz resonators. Each unit cell includes a Helmholtz resonator having a neck that places the resonator interior in fluid communication with an ambient fluid, in the lateral direction. Each Helmholtz resonator of the unit cell has a different resonance frequency, providing broadband reflection.
