Özet

In this letter, we devise a frequency, distance, and altitude-dependent, analytical model for THz band path loss. This model is obtained from cascaded regression of transmittance data from Line-by-Line Radiative Transfer Model (LBLRTM) propagation analysis tool, considering altitudes from the sea-level to 1 km, distances from 1 m to 100 m and frequencies within 0.79-0.91 THz and 0.93-0.94 THz. The proposed approach yields high accuracy with respect to propagation data while providing a simple, closed-form expression to help the design of Terahertz (THz) band drone communications.
