    A detailed theoretical analysis for planar bulk-acoustic-wave (BAW) devices that results in a method for computing the bulk-acoustic-wave response for any orientation of any piezoelectric substrate is presented. The BAW responses for four devices is computed and are found to be in excellent agreement with published experimental results. The theory is used to optimize one of these devices by varyin...

    A detailed field analysis is presented for a leaky surface wave propagating under a periodic metal grating, using a theory that neglects the effect of mass loading due to the grating. The approach is based on Floquet's theorem and the coupled equations of wave motion with unperturbed mechanical and perturbed (or periodic) electrical boundary conditions, yielding a general field solution applicable...

    A ferroelectric detector system was designed for measurement of dose rate in high-energy electron beams. It was found that a simple lead zirconate-titanate ceramic responds reproducibly to a chopped electron beam by ferroelectric conversion of the resulting pulsed temperature rise to a proportional output voltage. Response as a function of dose rate is linear, the rate of response being a function... View full abstract»

    The authors propose a technique that allows them to size bubbles with the same accuracy as with the double-frequency method and to locate them with the same range resolution as with the pulsed Doppler velocimeter. They demonstrate that the signal scattered by the bubble insonified by a high-frequency pulsed ultrasonic field and a low-frequency pumping field is a low-frequency signal sampled at the...

    Ring piezoelectric transducers generating ultrasonic energy in air were designed and tested experimentally and numerically. The radiation pattern of the transducer is very narrow (4 degrees ) and its frequency response has a broadband character. Resonant frequencies of the transducers were determined experimentally and verified theoretically. Applications of the proposed ring transducers in a robo... View full abstract»
