Abstract :
Additive manufacturing (3D printing) has been used to construct phononic crystals that operate in the 100 kHz - 1MHz frequency range. These were in the form of regular arrays and columns of steel spheres, embedded within a polymer matrix. Experimental measurements using coded waveforms in a water tank were able to demonstrate that focusing effects were present at certain frequencies, as expected from a phononic crystal structure.
