Magnetically coupled resonant wireless power transmission: An artificial transmission line approach

In this paper a wireless power transfer resonant link using inductive coupling is considered and analyzed on the basis of an artificial transmission line approach. More specifically, a periodic network consisting of inductively coupled LC resonators is studied. It is demonstrated that the analyzed system exhibits a pass-band characterized by negative effective parameters (i.e., a double negative pass-band). In order to validate the proposed approach, comparisons with experimental data and circuital simulations are reported and discussed.
