Two-Dimensional Transverse Magnetic Propagation Model of a Sine Wave Using MurBoundary Conditions

摘要

A two-dimensional (2-D) transverse magnetic formulation of a propagating sinewave source disturbance was numerically simulated using the finite difference-time domain (FD-TD) methodology. The nonreflecting boundary conditions due to Mur were used at the boundary surfaces. Electric field intensity distributions resulted over a progressive time expansion to illustrate the propagation effect over the entire 2-D mesh. The imposition of the Mur boundary algorithm produced accurate results when the second approximation was used and when the source was located reasonably far from the mesh boundary.
