摘要: Abstract The feasibility of using the band structure a crystal to realize directional emission water waves is investigated numerically and experimentally. directionality source inside square array cylinders obtained for perfect lattice in lossless liquid. But experiments, directivity weakened, due effects losses. Nevertheless, are shown satisfy Helmholtz equation when proper attenuation accounted for. Thus, robustness studied with respect disorder.
