Abstract
Terahertz time-domain spectroscopy of hydrogen bonded materials was carried out to investigate the dielectric and optical properties of materials in the THz frequency range. The complex dielectric constant (i.e., ε' and ε") of H2O ice, D2O ice, propane hydrate, SF6 hydrate and CH4 hydrate was measured at frequencies in the range 0.4-1.2 THz and temperatures in the range 20-240 K. We discuss the frequency and temperature dependence of ε' and ε" using a mathematical model to obtain specific parameters. These results show that it is possible to analyze the dielectric constants of gas hydrates using a mathematical model of ice.
