摘要
沉没液体水里的亚波长 Cu 电线栅栏,我们证明传播定量能从 0.1 THz 显着地被改变到 1.7 THz。由液体水的兆兆赫回答的调整被增加在电浆子图画解释有效电子质量。由于这回答,我们提取液体水的索引,并且我们的结果提供使用金属栅栏在 THz 频率范围检测真实 solvated 条件 biomaterials 的潜在的应用。[从作者抽象]
Submerging the sub-wavelength Cu wire grating in liquid water, we prove that the transmission ration can be changed pronouncedly from 0.1THz to 1.7THz. The modulation of terahertz responses by liquid water is explained by the increasing effective electron mass in the plasmon picture. Due to this response, we extract the index of liquid water, and our results provide a potential application of using metal grating to detect real solvated condition biomaterials in the THz frequency range.
