摘要：
A method is provided and includes exciting a sensor with an incident signal and generating a reflected signal by reflecting the incident signal from the sensor. The incident signal and the reflected signal interfere to form a standing wave. The method also includes processing the signals to determine a sensed parameter based upon a frequency at which the standing wave exhibits a null.
