In this paper, it is studied a range of complex permittivity values estimated from a Pinus Pinaster fuel bed on fire. The Fire Dynamics Simulator (FDS) was used to model the fire environment and the Cold Plasma Model (CPM) was applied
to evaluate the complex permittivity of such media. Effects of the found maximum and minimum permittivity magnitudes for the considered time step were explored using the Finite-Difference Time-Domain (FDTD) method to comprehend the impact of a weakly ionised plasma generated during vegetation combustion, on radiowave propagation.
