摘要

We have investigated the resonant properties of a composite meander wire array, which is composed of physically connected ‘metamolecules’ each with two face-to-face hetero-connected split-ring resonators (SRRs). The hybridization of the symmetric modes and antisymmetric modes of the two hetero-connected SRRs results in four resonant modes in the isolated ‘metamolecule’. In the chain case however, only the hybridized symmetric modes, the so-called optical modes, exist, leading to the observed trapped modes. These two trapped modes show an opposite frequency shift between the chain and isolated metamolecule. Numerical simulations and a theoretical analysis based on the hybridization model are used to interpret the underlying physics of the above observation. Our results provide a further understanding of the hybridization effect in complex metamaterials. The continuous morphology of our double-chain structure may be applied tp the design of reconfigurable metamaterials and flexible devices.
