ULTRASONIC INDUCED ARTIFICIAL BLACK HOLES IN PHONONIC CRYSTALS

摘要

Acoustophoretic devices and methods for using such devices in various applications are disclosed. The devices include a flow chamber having an inlet; a phononic crystal within an active volume of the flow chamber; and ultrasonic transducer(s) that create an acoustic standing wave in the active volume. This combination results in the creation of high-pressure nodes within the active volume, having a value of at least 50 MPa, which is useful for different applications.
