Radio coverage in the troposphere and urban areas has been a challenging problem for many years. Researches in wave propagation area have searching for efficient mathematical models for describing the problem of electromagnetic wave propagation in troposphere. Numerous methods are available for predicting electromagnetic wave propagation in the atmosphere. However, the presence of vertical refractivity stratification in the atmosphere complicates the application of some methods. To model refractivity variations in the horizontal as well as vertical direction, geometric optics, coupled-mode analysis or hybrid methods have been employed.
