The resonator is a Fabry-Perot cavity formed by two Bragg gratings, each consisting of 200 parallel stripes (shown in yellow) separated by half the acoustic wavelength. The wavelength is equal to ...

Acoustic resonators are more stable than their electrical counterparts, but they can degrade over time. There is currently no easy way to actively monitor and analyze the degradation of the ...

Cornell University researchers have finally figured out exactly how human hand claps create their distinctive sound — and it's far more sophisticated might think.

(Courtesy: Yu Yang/ETH Zurich) Researchers in Switzerland have created a mechanical qubit using an acoustic wave resonator, marking a significant step forward in quantum acoustodynamics. The qubit is ...

coherent control and Rabi oscillations—and with a couple-gigahertz acoustic resonator, map that onto the orbital states and see that those techniques are still valid." Fuchs's work helps advance ...

As they did, they noticed improvements in the acoustic’s performance, and yet still something was not right. For a start, those earlier experiments just didn’t look right. “As fans of ...

The recorded frequencies matched the predictions of the Helmholtz resonator model ... on their distinctive claps and use it as a kind of acoustic login for electronic devices.
