Tunable chevron-shaped infrared metamaterial

Abstract We propose two tunable chevron-shaped infrared metamaterials (CSIMs). The electromagnetic responses of CSIMs can be tuned linearly by changing the geometrical configurations. The correlation coefficients of CBIMs with different chevron beam lengths are 0.9999. Furthermore, CBIMs exhibit bidirectional tunability by changing the intersection angles of chevron beams. The corresponding resonance can be tuned to red-shift and blue-shift. This study provides an effective approach to open an avenue in switch, filter, sensor, and polarizer applications in infrared wavelength ranges.
