Abstract
In some implementations, a capacitive micromachined ultrasonic transducer (CMUT) apparatus includes one or more CMUTs or CMUT arrays, an acoustic window, a coupling medium, and a packaging substrate. The acoustic window may have various configurations, such as for reducing acoustic reflectance or increasing mechanical properties. In some examples, at least one of the CMUTs, the acoustic window or the coupling medium may include a focusing capability for focusing acoustic energy to or from the CMUT.
