我们报告说，不对称的C形孔显示模式切换之间的单，双共振频率在太赫兹区域，当入射光的偏振方向被控制。谐振频率的数量归因于基本形状模式，如圆形，同轴，和矩形形状的孔在每个偏振条件下激活。所有这些共振峰也显示出在周期性排列的孔的帮助下超过90%的透射率。这些实验结果与理论模拟结果非常吻合。
We report that asymmetric c-shaped holes show mode switching between single- and double-resonance frequencies in the terahertz region, when the polarization direction of the incident light is controlled. The number of resonant frequencies is attributed to fundamental shape modes such as circle-, coaxial-, and rectangular-shaped holes activated under each polarization condition. All of these resonant peaks also show a transmission of over 90% with the assistance of the periodically arranged holes. These experimental results are in close agreement with theoretical simulations.
