Paper Abstract

We theoretically investigate electromagnetic responses of a bilayered metamaterial in the optical frequency range. The metamaterial consists of two stacked split ring resonators with a twist angle spatially separated by a dielectric layer. The simulated results show that the bilayered metamaterial exhibits multiple transmission windows based on mutually coupling between two twisted resonators at normal incidence and the manifested transmission properties can be controlled efficiently by adjusting structural parameters of a unit cell. The coupling in metamaterials offers an effective way to manipulate the electromagnetic properties of metamaterial-based devices.
