Abstract
Metasurfaces in namo-meter are widely applied to improve the lightwave controllability. The reflection of the proposed planar nanotip metasurface in infrared regime was demonstrated to be effectively modulated, and the minimum value is ~41.0% under an infrared radiation of 4.74μm. Besides, the near-field resonance enhancement localized at the apex region was also discovered. The intensity of the near-field electronic component is demonstrated to reach a maximum value of ~75.4μV.
