|Title:||A tunable multiband chirped metasurface|
|Keywords:||Tunable;Metamaterials;Surface plasmon resonance;Chirp;Negative refraction|
|Abstract:||We numerically present a multiband double negative chirped metasurface (MS) in the near-infrared (N-IR) region. The MS was composed of a round nanoholes array (RNA) penetrating through metal/dielectric material/metal (AueAl2O3eAu) trilayers. The chirp was excited by varying the positions of the RNA along the direction of incident electric (E)field vector inside the meta-atom. It is found that besides a multi-band double negative refractive index (NRI), a spectral tuning of NRI is also unveiled by moving the neighbouring round holes closer to each other. Importantly, we also show that the chirped MS with large round hole resonators possesses a high value of the Figure-of-Merit (FOM) in the optical region|
