Abstract

The interaction of magnetic resonators connected by nano-antennas is studied for the first time. Compared to a simple magnetic resonator, the absorptance can be obviously much enhanced and more electromagnetic energy can be converged by the assembled magnetic resonator and nano-antennas (nano-strip). The nano-strip plays the role of both nano-antenna and phase tuner for propagating surface plasmon polaritons (SPPs). The interaction of localized surface plasmon resonance and propagating SPPs can remarkably be tuned by simply changing the width of nano-strips. When lattice coherence happens at the magnetic resonance, maximum enhancements of local field are achieved. This approach paves a new way for the design of a metamaterial based on magnetic resonators.
