  • Abstract
    A conical-horn, circular-waveguide coupler was designed and fabricated to couple THz radiation from spectrometers and concentrate it for low-volume samples. A demonstration was carried out on spores of Bacillus thuringiensis (Bt) - a bioparticle known to have strong signatures between 0.9 and 1.1 THz.
