Abstract :
THz stand-off detection of explosives and other hazardous liquids in public areas becomes more and more relevant and with it the knowledge of their optical properties. We present here both the results of THz transmission spectroscopy measurements and spectroscopic ellipsometry measurements on liquids and their mixtures.
