Popis: We demonstrate matched toroidal and magnetic dipole resonances in dielectric rod metasurfaces by combining an elliptical rod cross-section or a coupled-rod molecule with inter-cell coupling. Importantly, the resonances remain matched when varying the permittivity or rod radius, opening the possibility for wavefront shaping and tunable perfect absorption.
