Abstract
The experimental observation of acoustic stop bands in two-dimensional periodic arrays using an impulse response technique is reported. The frequencies of the stop-band centers are consistent with simple theoretical considerations based on the spacing between layers along the high symmetry directions of the regular arrays. The phase information extracted from the Fourier analysis is used to construct the acoustic dispersion relation for frequencies above and below the stop band. Measurements are reported for both square and triangular scattering arrays.
