Wet-etched phononic crystal waveguiding on GaAs
(IOP Publishing, 2018-01-10)
A wet-etched phononic crystal waveguide in GaAs with approximately two micron deep inclusions is studied both numerically and experimentally for controlled surface acoustic wave propagation. Numerically, the phononic crystal ...
Phononic Crystal Waveguiding in GaAs
Compared to the much more common photonic crystals that are used to manipulate light, phononic crystals (PnCs) with inclusions in a lattice can be used to manipulate sound. While trying to propagate in a periodically ...
