Abstract
A model for the complex transmittivity of tree crowns in the microwave band is proposed. Experimental technique and results of measurements of the tree branches complex transmittivity (module and phase) in the frequency band 0.8-8 GHz are presented. It is noted that an abnormal frequency dispersion of the refractive index is observed in the experiment that is connected with the resonance attenuation by branches.
