Abstract Absorption spectra (0.2-1.8THz) of the mixtures of explosive 2,4-DNT and polyethylene(PE) at different ratios are obtained using reflection terahertz time domain spectroscopy (THz-TDS). The pronounced absorption peak of 2,4-DNT at 1.08THz is always observed for the mixtures with 2,4-DNT ratios above 20%. Experimental results demonstrate that more applicable and realistic THz-TDS in reflection geometry can be used to distinguish explosive mixed with other material having no THz fingerprints, and has a high potential in the detection of explosives.
