Spectral Frequency Response of Hypersonic Phonons in a Non-Trivial Topological Waveguide

Résumé

The spectral frequency response of a hypersonic phononic wave propagating along a non-trivial topological waveguide is obtained by laser Doppler vibrometry. The guided mode at 2.115 GHz is shown to propagate with minimal loss.
