Research output: Contribution to journalConference articlepeer-review


Terahertz Time domain spectroscopy (THz-TDS) can provide the optical response of a medium in both amplitude and phase. We show that such capability can enable a detail analysis of optical properties of biological sample. Such study is important for standoff detection of presence of biological sample, where a detail analysis is difficult if not possible due to a complicated system involved and multiple effects involved. We proposed a transfer fonction study of the response of such system.
