Abstract

The terahertz dielectric properties of GaAs were tested in the frequency range extending from 0.23 THz to 0.375 THz by using backward-wave oscillator (BWO). The terahertz refractive indices, the absorption spectra and the dielectric functions of various resistivity GaAs were measured and compared. The experimental results indicate that the absorption coefficient of the GaAs is decreased with the frequency increasing and its least absorption coefficient equals 3.87x10^-4 cm^-1. Our results demonstrate that the applicability of the backward-wave oscillator THz absorption spectroscopy to GaAs characteristic analysis by calculating the absorption spectra. This work establishes the basic spectra data for GaAs is very significative to design the high efficiency terahertz wave antenna.
