[19p-E215-11] Observation of Phase Change of Methane Hydrate Using THz Waves

Keywords:Methane Hydrate, THz-TDS

We observe a phase change of methane hydrate, which is expected to be a new energy resource, using THz Time-Domain Spectroscopy (THz-TDS). In the temperature zone where methane hydrate should be decomposed, an increase in absorption and a shift in time-domain waveform are observed, which seems to indicate that the sample is mutated.
