Example Sentences

Liao and Yang's innovative technique allows simultaneous monitoring of multiple resonant modes within a single WGM resonator, considering distinctive responses from each mode, vastly expanding the range of measurements achievable.

From Science Daily

Instead of a traditional ad, he and a pal put together a series of property-crime skits with just a car and two actors — plus an exhaust resonator meant to stand in for a stolen catalytic converter.

From Los Angeles Times

Mechanical vibrations oscillating between two mirrors in a resonator can be cooled to very low temperatures as far as the quantum ground state.

From Science Daily

By carefully engineering the design of the silicon structures, the result is a self-assembled resonator with bowtie-shaped gaps at the atomic scale surrounded by silicon mirrors.

From Science Daily

"We are far from a circuit that builds itself completely. But we have succeeded in converging two approaches that have been travelling along parallel tracks so far. And it allowed us to build a silicon resonator with unprecedented miniaturization," says Søren Stobbe.
