Background,Motivation and Objective We investigate the approach of how to build a 1D phased micromachined ultrasonic transducer array that is able to receive directed ultrasonic waves in air over a wide opening angle at frequencies of 40 kHz and below.Such a low frequency range is beneficial because of the low attenuation.
