Anisotropic propagation of GHz surface and bulk acoustic waves in gallium arsenide studied by random scattering
T. A. Steenbergen, M. M. Wohlfarth, P. E. Veefkind +3
Understanding the complex anisotropic acoustic propagation in crystals is crucial for optimizing the performance of surface and bulk acoustic wave devices. Here, we investigate the…
Young's double-slit experiment with anisotropic GHz surface acoustic waves on gallium arsenide
Thomas Steenbergen, Matteo Fisicaro, Krystian Czerniak +3
We demonstrate Young's double-slit experiment with GHz surface acoustic waves (SAWs) on gallium arsenide (GaAs). This experiment differs from the well-known optical case due to the…
Observation of the Talbot effect from a surface acoustic wave dynamic grating
M. Fisicaro, Y. C. Doedes, T. A. Steenbergen +2
We demonstrate the dynamical Talbot effect caused by optical diffraction from standing surface acoustic waves (SAWs). The Talbot effect is a wave interference phenomenon in the Fre…
Imaging transverse modes in a GHz surface acoustic wave cavity
M. Fisicaro, T. A. Steenbergen, Y. C. Doedes +2
Full characterization of surface acoustic wave (SAW) devices requires imaging the spatial distribution of the acoustic field, which is not possible with standard all-electrical mea…
