Abstract

A planar dipole array on low-temperature (LT) growth gallium arsenide (GaAs) or cyclo olefin polymer film is analyzed for magnetic terahertz surface wave, TE wave propagation. A laser pulse excites the dipole gap in order to generate photo carriers on the surface of a LT-GaAs photoconductive substrate. A dipole array on the LT-GaAs substrate is designed for a surface wave around 0.40 THz. The analysis also derives the dispersion diagram and transmission loss. The dispersion diagram indicates that propagation of the surface wave is confined around the dipole elements. The dipole array on a cyclo olefin polymer film can be also designed at around 0.45 THz.
