THz Time-Domain Spectroscopy, THz Coherent Transients and THz Impulse Ranging

该计划侧重于应用太赫兹时域光谱（TDS）来解决傅立叶变换光谱（FTS）无法解决的实验问题。将从实验和理论两方面对太赫兹- tds和FTS进行详细的比较。此外，目前对相干瞬态的研究将扩展到瞬态物质和自由基。通过对介电球对电磁辐射散射的表面波贡献的理论预测的第一次直接实验测试，引入了太赫兹脉冲测距的新主题。

This program focuses on the application of THz time-domain spectroscopy (TDS) to experimental problems that cannot be solved by Fourier Transform Spectroscopy (FTS). A detailed comparison between THz-TDS and FTS will be carried out both experimentally and theoretically. In addition, a current effort in coherent transients will be extended to include transient species and free radicals. A new topic of THz impulse ranging will be introduced through the first direct experimental test of theoretical predictions for the surface wave contributions to the scattering of electromagnetic radiation by dielectric spheres.
