Abstract

The effects of rain attenuation on 0.1- to 1-THz frequencies are reported in this paper. The THz pulses propagate through a rain chamber over a 4-m distance and are measured by THz time-domain spectroscopy (THz-TDS). A rain chamber is designed to generate controllable and reproducible rain conditions with different intensities. Image analysis software is employed to characterize the distribution of generated raindrop sizes. Theoretical THz power attenuations due to rain are calculated using Mie scattering theory and are compared with our measurements. Results show that both experimental and theoretical results are in very good agreement with each other.
