Abstract : A set of hybridized resonators is used to achieve efficient and tunable far field scattering control in the radiofrequency range. We demonstrate theoretically a full overlap between the electric dipolar and magnetic dipolar resonances of the meta-atom. This interaction is precisely tuned to reach the so-called Kerker scattering conditions when illuminated by a plane wave. Future work will tackle the illumination from a near field distributed source as the final goal of this study is to insert this element to control the radiofrequency electromagnetic field within a MRI birdcage coil.
