This paper aims at the development of a novel ray-tracing based method to characterise and model the electromagnetic behaviour of trees and vegetation volumes. This model uses various point scatterers with specific radiation characteristics, distributed within a computational volume, to describe the effect of the trees present in the radiowave propagation path. Additionally, the method to extract the parameters of the point scatterers from measurements is presented. The performance of this novel formulation was assessed in a tree formation scenario against measurements results obtained in a controlled environment, inside an anechoic chamber, at both 20 and 62.4 GHz.
