摘要：
Metasurfaces with high transmission performance are widely applied in photoelectric conversion, sensing, light modulation, and other fields. Here, the effect of local electric field resonance behaviors on the transmission performance of the metasurface is revealed and verified. The incident electromagnetic wave interferes with the oscillating charge distributed in the metal hole array, and a significant bright-bright coupling effect is stimulated by these local electric field resonance behaviors. A temperature-sensitive dielectric SrTiO3 (STO) layer is applied in this metasurface structure. By increasing the temperature, these original local electric fields are strengthened and a new bright-bright coupling effect is excited. Original transmission peaks are merged into a transmission band and new transmission peaks can be obtained.
