A phononic crystal device is investigated as a sensor platform combining band gap engineering with resonant transmission. A slit cavity perpendicular to the propagation direction of ultrasound and placed in the middle of a phononic crystal causes a peak in the transmission spectrum with the peak frequency strongly dependent on the speed of sound of the… (More)
