A reflector stack or acoustic mirror arrangement for an acoustic device is described which may attain the highest possible impedance mismatch between alternating higher and lower impedance reflecting layers of the stack, so as to maximize bandwidth.

This invention relates to a method and apparatus for imaging acoustic fields in high-frequency acoustic resonators. More particularly, the invention is directed to a scanning RF mode microscope system that detects and monitors vibration of high frequ

Sonoluminescence is an off-equilibrium phenomenon in which the energy of a resonant sound wave in a liquid is highly concentrated so as to generate flashes of light. The conversion of sound to light represents an energy amplification of eleven orders

Femtosecond pulsed Mie scattering and a needle hydrophone have been used to probe the behavior of a light‐emitting bubble near that moment when the stress of implosion is at a maximum. It is found that the wall of the bubble is collapsing with a ve

Previous measurements have demonstrated that a small noble gas concentration is essential to the attainment of stable bright sonoluminescence from bubbles formed in a water nitrogen mixture. As the chemical properties of nitrogen and oxygen are quite

Now that the exciting measurements of picosecond flash widths, clocklike emission, broadband ultraviolet light, and the role of noble gas doping have generated substantial interest and theories for sonoluminescence, it is time to take a more sober lo
