Title:
電磁共振センサー
Document Type and Number:
Japanese Patent JP5014119
Kind Code:
B2
Abstract:
An electromagnetic resonant sensor has a dielectric sensor body through which electromagnetic wave energy is propagated. The sensor body has a cavity, with surfaces facing one another to define a gap that varies as a function of a parameter to be measured. The resonant frequency of an electromagnetic standing wave in the body and the variable gap changes as a function of the gap dimension.
