This experimental research program is aimed at new efforts in Terahertz (THz) Photonics and Surface Plasmons, which have evolved from the group's THz time-domain spectroscopy (THz-TDS) measurements of metal hole arrays and THz-TDS characterizations of the TEM-mode of the parallel plate waveguide. Using waveguide THz-TDS, the group has characterized with record sensitivity a 20 nm layer of adsorbed water, thereby opening new opportunities. They plan the first propagation measurements of THz surface plasmon waves, by using their multiple reflections to generate a train of freely propagating THz pulses. Overall they propose extremely sensitive waveguide THz-TDS measurements of adsorbed molecules, surface layers, Langmuir Blodgett films, films of metals, alloys, and conducting polymers. The broader impact of the program lies in the applications and in science education.

该实验研究计划旨在太赫兹（THz）光子学和表面等离子体的新努力，这些努力是从该小组的金属孔阵列的THz时域光谱（THz-TDS）测量和平行板波导TEM模式的THz-TDS表征发展而来的。使用波导THz-TDS，该小组以记录灵敏度表征了20 nm的吸附水层，从而开辟了新的机会。他们计划THz表面等离子体波的第一次传播测量，通过使用它们的多次反射来产生一系列自由传播的THz脉冲。总的来说，他们提出了非常敏感的波导THz-TDS测量吸附分子，表面层，朗缪尔Blodgett膜，金属，合金和导电聚合物的膜。该计划更广泛的影响在于应用和科学教育。
