An Unconditionally Stable WLP-FDTD Model of Wave Propagation in Magnetized Plasma

摘要

The weighted Laguerre polynomials-based finite-difference time-domain algorithm is applied for modeling wave propagation in a magnetized plasma medium. Its anisotropic property is treated by solving a set of tightly coupled current densities components implicitly at each iteration step. The equations are formulated in a stretched-coordinate system for the implementation of perfectly matched layer. Numerical examples validate the accuracy and efficiency of the developed algorithm.
