Abstract
A terahertz (THz) conical horn waveguide coupler was designed, fabricated, and tested for analysis of THz (100-1700GHz) vibrational modes of chemical and biological materials with small mass (<;1mg) or small volume (<;0.1μL). The waveguide concentrates THz fields, which excite stronger interactions with the samples. As examples the spectra of lactose, thymine, Bacillus thuringiensis and E. coli are presented.
