Electrodynamic analysis of resonance tags for radio-frequency identification of objects based on the method of singular integral equations

Abstract

Electrodynamic analysis of resonance radio-frequency identification tags in the form of a system of plane concentric metal rings is presented. The analysis is based on the method of singular integral equations. The patterns of the structure and frequency dependences of the response of tags with various code combinations are obtained and studied. The results provided by the method of singular integral equations and finite-difference time-domain technique are compared. It is shown that the proposed method makes it possible to substantially optimize the analysis of the considered identification tags through minimization of the computation time.
