Controllable Lorentz Force via Mutual Inductance in Split Ring Resonators

Magnetic interactions in metamaterial structures have led to a wide variety of applications from wireless power transfer to contactless localisation. Here, we show that in two split ring resonators (SRR), the direction of the induced Lorentz force can be reversed by varying the frequency of the applied AC voltage. An analytical model has been verified by experimental data. These findings have the potential to enable the reconfiguration of programmable structures for new capabilities and functionalities.
