Study of electronmagnetic pulse propagation in ionosphere using 2D PSTD

摘要

In this paper, 2D the pseudo-spectral time domain (PSTD) algorithm is applied to simulate propagation of line-source in each layer of ionosphere, which is used to solve the equations of cold plasma. The excitation source is applied to eliminate Gibbs phenomenon, which is used by a compact wave source condition. The results are significance to propagation of line-source in ionosphere.
