Tailored Resonator Coupling for Modifying the Fundamental Resonance in Laterally Coupled Terahertz Metamaterials

摘要

We experimentally and numerically study the nature of coupling between laterally paired terahertz metamaterial split-ring resonators. Coupling is shown to modify the inductive-capacitive (LC) resonances resulting in either red or blue-shifting. These experiments illustrate additional degrees of freedom in tuning the electromagnetic response of metamaterials.
