Abstract
Systems for directional surface acoustic wave transmission are disclosed herein. In one example, a system includes a transmitter configured to transmit a surface acoustic wave and a receiver configured to receive the surface acoustic wave. A resonant structure may be disposed on the surface of a substrate between the transmitter and receiver and is configured to allow the surface acoustic wave to propagate through the resonant structure towards the receiver and limit a reflection of the surface acoustic wave to propagate through the resonant structure towards the transmitter.
Claims20
A system comprising:
- a transmitter configured to transmit a surface acoustic wave;
- a receiver configured to receive the surface acoustic wave;
- and
- a resonant structure disposed on a surface of a substrate between the transmitter and receiver, the resonant structure configured to allow the surface acoustic wave to propagate through the resonant structure towards the receiver and limit a reflection of the surface acoustic wave to propagate through the resonant structure towards the transmitter.
A resonant structure configured to allow a surface acoustic wave to propagate through the resonant structure in a first direction and limit a reflection of the surface acoustic wave to propagate through the resonant structure in a second direction.
