Time-domain imaging of gigahertz surface waves on an acoustic metamaterial

Time-domain imaging of gigahertz surface waves on an acoustic metamaterial

We extend time-domain imaging in acoustic metamaterials to gigahertz frequencies. Using a sample consisting of a regular array of ~1 μm diameter silica microspheres forming a two-dimensional triangular lattice on a substrate, we implement an ultrafast technique to probe surface acoustic wave propaga...
