A1 - Beckmann, Jörg T1 - Spectroscopic ellipsometry on liquids in the far infrared T2 - International Conference of Infrared Millimeter AND THz waves N2 - The far infrared refractive indices and the extinction coefficients of liquids can be obtained by means of spectroscopic ellipsometry in attenuated total reflection configuration. Such optical constants will contribute to a spectroscopic data base in the far infrared and terahertz spectral regions. The experimental implementation and the calibration procedure of the method are described in detail. The temperature dependency of the optical constants for water over a broad spectral range is exemplarily presented.
