Abstract

The absorption coefficient and refractive index of tourmalinein different directions were characterized for the first time usingterahertz time-domain spectroscopy. Results show that the absorptionand refractive index of terahertz frequency are related to the structureof tourmaline. Absorption along the optical axis direction is moresensitive than that along the vertical direction. This result indicatesthat the identification and characterization of crystals as well asminerals can be realized by the terahertz method.
