Abstract: A method and structure for a radio frequency identification (RFID) system including an RFID tag. The RFID tag can include a dampener configured to dampen a resonation of a resonator. Prior to dampening the resonation of the resonator using the dampener, the RFID tag may be configured to transmit a first response signal from a transmit antenna. Subsequent to dampening of the resonation of the resonator using the dampener, the RFID tag may be configured to transmit a second response signal that is different from the first response signal. The dampener may include a chemical agent or a fusible link.

Abstract: A chipless RFID transponder is disclosed. The transponder comprises an antenna and a plurality of resonant structures that together define a spectral signature of the RFID transponder. Each of the resonant structures comprises conductive portions separated by interstitial regions. A reversible photoconductive material is disposed in the interstitial regions of the resonant structures between the conductive portions. The photoconductive material is positioned so as to shift the spectral signature of the RFID when exposed to radiation.
