| Research Abstract |
We investigated the stripline structures for high sensitivity and local sensing of matter using terahertz waves. On the high sensitivity sensing, we demonstrated that both the microstrip and coplanar line filters are equally useful and that, by utilizing a differential detection scheme with split lines, the sensitivity of time domain spectroscopy can be improved by about one order of magnitude. On the local sensing, we showed that the spectroscopic sensing becomes possible with a spatial resolution of 1/100 wavelength using a metal probe integrated on the striplies.
