Rain Attenuation at Terahertz
TLDR
Rain attenuation values were calculated using empirical raindrop-size distributions, and also calculated using a specific rain attenuation model for prediction methods recommended by ITU-R, and showed that the propagation experiment was in very good agreement with this calculation.Abstract:
Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a specific rain attenuation model for prediction methods recommended by ITU-R. Measurements of Terahertz wave taken at 313 GHz (0.96 mm) were compared with our calculations. Results showed that the propagation experiment was in very good agreement with a calculation from the specific attenuation model for use in prediction methods by ITU-R.read more
