摘要：本文分别从实验和理论模拟两方面详细的讨论了金属双环和反双环两种亚波长阵列结构在太赫兹波段的双频率响应特性.这两种双环结构都可以实现双频率调制,金属双环结构表现为两个明显的吸收峰,反双环结构则表现出明显的透过峰.这两种结构不仅在物理结构上互补,在太赫兹波段的响应也表现为吸收和透过互补的特性.其中高频响应来源于内环电子振荡,低频影响则来源于外环电子振荡,并且这种结构在太赫兹波段的响应与周期无关.
This paper deals with the dual- band response of double ring metal array structure and anti-double ring structure in a terahertz wave range. The two samples are complementary in structure and their responses in the terahertz band are also complementary. The double ring structure shows two absorption crests and the anti-double ring structure shows two corresponding peaks at the same frequencies. The inner ring of the double ring structure is a source of high-frequency response, while the outer ring leads to the low-frequency vibration. Therefore, we can change the inner and the outer ring size respectively to control the terahertz response. And this response is unaffected by the period of the structure. The double ring structures provide a new method to produce multi-frequency terahertz resonator.
