Modeling electromagnetic wave propogation in 3D environments

In this paper a method is developed to model two-way propagation of eletromagnetic waves. A recursive algorithm based on the Split Step Parabolic Equation Method (SSPE) is introduced. This algorithm both simplifies the implementation of the two-way propagation algorithm and also reduces the computational complexity. The terrain is modeled using a staircase approximation and also the targets are modeled using simple geometric shapes to investigate their effects on propagation. The proposed method is also used to model three-dimensional propagation on real terrain data using multi-core processors.
