ELECTROMAGNETIC RESONANT SENSOR |
摘要 |
An electromagnetic resonant sensor (800) has a dielectric sensor body (802) through which electromagnetic wave energy is propagated. The sensor body (802) has a cavity, with surfaces facing one another to define a gap (810) that varies as a function of a parameter to be measured. The resonant frequency of an electromagnetic standing wave (814) in the body (802) and the variable gap (810) changes as a function of the gap dimension. |
