Conductivity of leaves and branches and its relation to the spectral dependence of attenuation by forests in meter and decimeter band

摘要

Conductivity of leaves (needles) and branches of different trees as well as conductivity of their sap was directly measured. Measuring technique is presented. Measured values of needles and branches conductivity are several times less than these values recalculated from sap conductivity values by known models. Influence of leaves and branches conductivity value on the spectral trend of radio waves attenuation by foliage is discussed in this paper.
