Parallel plate THz transmitter
(AIP Publishing, 2004-02-02)
A THz transmitter that directly excites the guided wave modes of a dielectric filled parallel plate waveguide is demonstrated. When coupled to free space, the transmitter yields a large peak time-domain THz signal. The ...
THz Zenneck surface wave (THz surface plasmon) propagation on a metal sheet
(AIP Publishing, 2006-02-08)
We present an experimental study of the propagation of the THz Zenneck surface wave on an aluminum sheet, now more commonly denoted as the THz surface plasmon (TSP). Here, the TSP pulse is generated by coupling the THz ...
Planar THz quasioptics
(AIP Publishing, 2004-08-09)
Two-dimensional (2D) quasioptical elements are demonstrated as guiding structures in the THz frequency regime. A planar polyethylene lens is incorporated in a parallel metal plate structure and is shown to focus guided THz ...
THz Sommerfeld wave propagation on a single metal wire
(AIP Publishing, 2005-04-12)
We report an experimental and theoretical study of THz Sommerfeld wave propagation on a single copper wire. THz pulses are optoelectronically generated and launched onto 0.52-mm-diam copper wire, and the guided THz pulses ...
