• 論文の詳細を見る

• The absorption spectra of smoke emitted from heated nylon fabric are studied in the sub-terahertz band. The transmission loss of 1.5-μm-wavelength light in the smoke is 50 dB/m or more. Even in such dense smoke, the loss for waves with the frequency ranging from 200 to 500 GHz is so small that absorption lines of gas molecules in the smoke can be detected in this frequency range. Spectral analysis indicates that the smoke contains molecules of toxic gas, such as HCN and CH3CN, generated due to incomplete combustion of the nylon fabric when heated to 500 °C with air.
