Abstract

This article outlines a radio-wave propagation model for VHF/UHF based on the dyadic Green´s functions. A three-layered medium was considered to characterize the path in a better way. Dyadic is a powerful tool for solving problems in the area of electromagnetism that allows properties of the medium to be incorporated. The study also takes account of the anisotropic medium. The proposed model has a good performance, presenting a small RMS error. A measurement campaign was conducted, together with comparisons with traditional models to validate the model.
