Abstract
A system and a method for measuring properties and health of structures are disclosed. The system comprises a number of sensors connected to a single antenna. Each sensor has a body that defines an electromagnetic resonator. The electromagnetic resonator produces a response signal in response to an interrogation signal. The body is coupled to the structure to so as to allow the parameters of interest alter the resonance properties of the electromagnetic resonators thereby altering the response signal. The sensor further includes a coupler that is coupled to the body. The coupler transfers the interrogation signal into the electromagnetic resonator and transfers the response signal from the electromagnetic resonator. The system further includes an interrogator that generates and transmits the interrogation signal to the sensor. The interrogator also receives the response signal.
