Abstract
An array of acoustic transducing unit cells configured with an acoustic focus or a beam steering orientation. A variety of time delays between consecutively coupled acoustic transducing unit cells provides acoustic focus. In another configuration, a resistive signal path between adjacent acoustic transducing unit cells can be used to acoustically steer an acoustic beam in a direction non-normal to the top surface in which the array is disposed. In a further embodiment, a signal pad is made available at each end of the connections through an array of capacitive micromachined ultrasonic transducing unit cells.
