Unique Applications of THz Time-Domain Spectroscopy and Waveguide THz-TDS

该奖项为继续将该小组开创的THz时域光谱（THz-TDS）技术和波导Thz-TDS新技术应用于几个问题的项目提供资金。 其中包括研究相干太赫兹脉冲在分子蒸汽中的传播，斯塔克效应与TEM模式的线性和非线性太赫兹传播在一个平行板金属波导内的蒸汽细胞的组合作用，和测量导电聚合物的复电导率。 此外，该研究将涉及线性和非线性太赫兹相干瞬态的新努力，以及由硅圆柱体回音壁模式的相干叠加组成的太赫兹脉冲传播的实验研究。

This award provides funds for the continuation of a project in applying the THz time-domain spectroscopy (THz-TDS) technique pioneered by the group, and a new technique of waveguide Thz-TDS, to several problems. Among these are included the study of coherent THz pulse propagation in molecular vapors, the combined action of the Stark effect together with TEM-mode linear and nonlinear THz propagation on a parallel plate metal waveguide within a vapor cell, and measurements of the complex conductivity of conducting polymers. In addition, the research will involve new efforts in linear and nonlinear THz coherent transients, and the experimental study of the propagation of a THz pulse consisting of a coherent superposition of whispering gallery modes of a silicon cylinder.
