“…This way, by employing wavelet transforms, this method can efficiently decompose the radiowave interactions into different scales and frequencies, allowing for a more precise and detailed analysis of wave propagation and multi-path effects [14][15][16][17][18][19]. Moreover, numerous studies [20][21][22][23][24] have examined in detail how radiowave diffraction is specifically affected by trees, which create natural obstacles. Crucially, the study of radiowave diffraction in residential areas that comprise both vegetation and buildings must consider the attenuation effects due to trees, especially their canopies.…”

This article introduces a uniform theory of diffraction–physical optics (UTD–PO) formulation for analyzing radiowave multiple diffraction emanating from trees and buildings in green urban areas, considering illumination from a low transmitter and assuming spherical-wave incidence. Based on Babinet’s principle, this solution models buildings as rectangular sections and accounts for the influence of tree crowns (assuming these rise above the average rooftop height) by incorporating appropriate attenuation factors/phasors into the diffraction phenomena of buildings. The validation of the formulation is achieved through measurements made at the 39 GHz 6G mmWave frequency on a scale model of a green urban environment comprising bonsai trees and bricks. The main advantage of the proposed solution is that the calculations only include single diffractions due to recursion, circumventing the need to use higher-order diffraction terms in the diffraction coefficients, thus reducing the computation time and power. Our results may be beneficial for the design of mobile communication systems, including 6G networks, situated in green urban areas and with transmission source positioned lower than the surrounding infrastructure.
