A high performance MPI implementation of numerical modeling of electromagnetic scattering from forest environment

Abstract

The Message Passing Interface implementation ensures a reduction of the computing time and a distribution of the necessary memory to each processor. The 3D full-wave model for electromagnetic scattering from forest environment, based on the volumetric integral Equation formulation of the electric field, combined with the Characteristic Basis Function Method (CBFM) and implemented in Message Passing Interface (MPI) parallelization is described in this paper. This combination of the CBFM and the Method of Moments (MoM) allows us to reduce significantly the size of the initial electromagnetic scattering problem.
