Abstract
An electromagnetic sensor system. The system includes an electromagnetic excitable structure that generates an acoustic signal when irradiated with electromagnetic energy; an acoustic energy transducer sensor for generating a first output signal that represents the acoustic signal in response to the acoustic energy transducer detecting the acoustic signal; and a processor for determining whether the electromagnetic excitable structure is being irradiated by the electromagnetic energy in response to the processor receiving the first output signal.
