Paper Abstract

THz spectra of two pure materials and some mixed explosive materials and the theoretical analysis results are introduced. The refractive index and absorption coefficient of the samples are measured in the region of 0.2-2.5 terahertz by time-domain spectroscopy (THz-TDS). The absorption spectra are obtained correspondingly. The obtained results indicate the THz-TDS technology can identify the different explosives and roughly analysis the main ingredients of the mixed samples.
