METHODS AND SYSTEMS USING POLARIZATION MODULATED ELECTROMAGNETIC WAVES

摘要

Methods and systems using polarization modulated electromagnetic waves. At least some of the illustrative embodiments are systems comprising a radio frequency identification (RFID) reader, and a RFID tag (the RFID tag communicatively coupled to the RFID reader). The RFID tag is configured to transmit data to the RFID reader with data encoded in polarization of electromagnetic waves transmitted from the RFID tag.
