摘要：

We examine the transmission and reflection of surface acoustic waves from a two-dimensional hexagonal lattice. Highly anisotropic signals are observed by continuously scanning the wavevector angle. Preliminary models of wave propagation through this phononic lattice predict the acoustic dispersion and a complete band gap; however, the experimental results indicate that more realistic modeling of surface acoustic waves in elastically modulated media is required.
