Abstract
The vibration modes of air-medium ultrasonic sensor with a multi-vibration disc and the counteraction effect of the two phase-reversal regions of the disc are analyzed in this paper. A new air-medium type of ultrasonic sensor, with a resonant air gap of λ/2, is proposed. The operation theory and the experimental results of the sensor are also presented.
