中文摘要:
在有在兆兆赫(THz ) 的二个明亮的模式和一个黑暗模式的 metamaterial 共鸣器的电磁地导致的透明性(EIT ) 乐队数字地并且试验性地被表明。与二种有点被动的调整不同,我们的设计能由增加另一个明亮的模式共鸣器认识到 EIT 现象的被动调整。模仿并且传播山峰为事件 THz 改变的试验性的结果表演由于它的不对称的结构与不同极化方向飘动,它提供一个新奇方法认识到高效率开关和调整。
英文摘要:
An electromagnetically induced transparency(EIT) in metamaterial resonator with two bright modes and one dark mode at the terahertz(THz) band is numerically and experimentally demonstrated. Different from two kinds of the traditional passive modulations, our design can realize the passive modulation of EIT phenomenon by adding another bright mode resonator. Simulated and experimental results show that the transmission peak varies for incident THz waves with different polarization directions due to its asymmetric structure, which provides a novel way to realize high efficiency switch and modulation.
