Quite recently, it was found that metal wires can effectively guide terahertz radiation. Based
on the fact that the absolute values of the relative permittivities of metals in the spectral …

The authors present measurements and calculations on the effect of thin dielectric coatings
on the propagation of terahertz pulses along the surface of metal wires. Our measurements …

The nanofocusing of the terahertz (THz) radiation energy is studied. By using a conical metal
nanowire waveguide, we focus the energy of the terahertz surface plasmon polaritons (THz …

We report on the emission patterns from THz plasmons propagating towards the end of
cylindrical metal waveguides. Such waveguides exhibit low loss and dispersion, but little is …

The development of effective techniques for guiding pulsed terahertz radiation is essential
for the continued development of terahertz spectroscopy and imaging applications based on …

Wire waveguides have recently been shown to be valuable for transporting pulsed terahertz
radiation. This technique relies on the use of a scattering mechanism for input coupling. A …

We propose a metamaterial approach to route terahertz waves that features subwavelength
confinement in the transverse plane. The guiding mechanism is based on geometrically …

We investigate the propagation properties of terahertz plasmon of a metallic nanowire with
sub-skin-depth diameter. By taking the small radius and the huge relative permittivity into …

We report on the terahertz transmission properties through a single slit in a thin metallic film.
The properties are studied by comparing the transmissions of TE-and TM-polarized …

Because of their long propagation length at a metal surface in the far infrared, surface
plasmons make potentially feasible the design and realization of 2D integrated terahertz …
