The Simulation of Electromagnetic Scattering Using CFD-Based Unstructured Grid Methods

摘要

The simulation of the scattering of plane electromagnetic waves by two-dimensional obstacles is considered. The governing equations are Maxwell's equations expressed in the conservation form. The solution is obtained by modifying techniques originally developed for the compressible Euler equations on the triangular unstructured grid. The computed time domain solution is then transformed to frequency domain to determine the bistatic scattering width of the obstacle. The computed results agree well with the theoretical solutions.
