A Three Dimensional FDTD Algorithm for Wave Propagation in Cold Plasma Media using Forth-Order Schemes

摘要

A fourth-order accurate in space and second-order accurate in time, finite-difference time-domain (FDTD) scheme for wave propagation in cold plasma media is presented. The formulation of Maxwell's equations is fully described and an elaborate study of the stability and dispersion properties of the resulting algorithm is conducted. The efficiency of the proposed FDTD (2, 4) technique in cold plasma media compared to its conventional FDTD (2, 2) counterpart is demonstrated through numerical results.
