Schaafsma, M.C. (author), Starmans, H. (author), Berrier, A. (author), Gómez Rivas, J. (author)We demonstrate experimentally the resonant extinction of terahertz (THz) radiation by a single plasmonic bowtie antenna, formed by two n-doped Si monomers with a triangular shape and facing apexes. This demonstration is achieved by placing the antenna at the output aperture of a conically tapered waveguide, which enhances the intensity of the...journal article 2013
