Short summary
In this paper, wireless power and data transmission through coupled magnetic resonators is investigated. Measurements on a simple prototype lead to a simplified schematic model. Based on this, the transfer channel's behaviour is modeled for arbitrary channel states (e.g. transfer distances) and can be fitted into a mathematical model. This is finally used to show that shifting the resonant frequencies of the individual resonators is a good means to ensure stabele data and energy transmission.
