Height Dependence of Electromagnetic Field inside the Forest Canopy at Meter and Decimeter Wavelengths

“…Though some more measurements have to be performed in order to better understand the impact of frequency variations on the height dependences observed. It is worth noticing that relevant considerations on this problem are available from papers [2][3][4][5][6]. Nevertheless, it was a distinct tendency for the field amplitude to grow with the height of receiver that took place in the case of prevailing lateral wave propagation mechanism.…”
