Near Field Resonator Isolation System: Theory to Implementation

The absence of electromagnetic wave motivates various studies of new communication channels in near field regime. An approach studied here is based on resonant inductive coupling and the use of Resonator Isolation (RI) system. The main concept of the RI system is to physically isolate two inductively coupled resonators from the signal input/output components. The resonators are charged with initial energy, and communicate by exchanging this energy according to the fundamental phenomenon of electromagnetic theory. Analyzing the energy exchange phenomenon, this paper presents two corresponding communication channel models for the RI system. Based on these channel models, the system architecture of the RI system is implemented at a chip level which consists of three components: resonator, analog switch, and digital process.
