Radio Frequency Identification (RFID) is a method of using radio frequency electromagnetic waves to automatically identify and track RFID tags attached to objects. Currently, RFID technology is used in payment systems, biometric identification documents, logistics and many other applications.
The main goal of our activity is to develop a new generation of effective and miniature RFID tags that surpass existing analogues. One of our directions is the development of a new type of RFID tags using miniature resonators based on dielectric materials with a high refractive index instead of metal resonant antennas, which, due to fundamental restrictions, cannot be much smaller than the wavelength of the incident radiation. Our goal is to bypass those limits by utilizing displacement currents in high-epsilon ceramics instead of conduction currents in metals. This significant and conceptual step will allow reducing sizes of tags by orders of magnitude, making them attractive to many practical applications.
