Abstract
A radio frequency identifier (RFID) tag is provided for receiving and reflecting electromagnetic energy at select frequency bands of visible and infrared wavelengths. The RFID tag includes an electrically conductive backplane; a dielectric substrate disposed on the backplane; a light guide film (LGF) disposed on the substrate, and metamaterial elements. The LGF has an exposed surface segregated into domains. The metamaterial devices are disposed on a domain. Each device is tuned to respond to a corresponding frequency among the select frequency bands.
