Abstract
This article aims to practically assess the point scatterer formulation to characterize the electromagnetic behavior of ornamental plants with varying thickness at 60 GHz. The proposed propagation model uses various point scatterers with specific radiation characteristics, distributed within a computational area, to describe the effect of the plants present in the radiowave propagation path. Additionally, a ray-tracing-based engine is used to gather all the interactions between the point scatterers present in the simulation channel. The performance of the proposed modeling approach is assessed against reradiation measurements of single and isolated plants, performed in the 60-GHz frequency band, inside an anechoic chamber. Additional model validation is obtained from reradiation measurements of several clumps of plants, mimicking specimens with varying thickness.
