Abstract
We report on dynamic properties of supported phospholipid membranes, using a spectroscopy technique based on terahertz surface guided waves. The transmitted spectra clearly show not only signal decrease of about 10% due to water absorption, but also transmission dips caused by the vibrational motions of membrane molecules.
