Abstract :
This work presents results involving the application of the CSB-MoM, a new hybrid complex source beam moment method, as an algorithm that analyzes propagation and scattering problems over large terrains. Thus, the formulation of the CSB-MoM is presented and then applied to a two-dimensional terrain profile. It is shown that the method can successfully reduce the memory and storage requirements, as well as average CPU time to a scale of O(N3/2) as opposed to O(N2) of the standard MoM.
