Fundamental Higher Order Weaker HIE-PML Algorithm for Magnetized Plasma

A fundamental weaker hybrid implicit-explicit algorithm is proposed to analyze single-direction-fine magnetized plasma. To accurately calculate the unique anisotropic constitutive relationship inside the magnetized plasma, the approximate bilinear transform method is introduced based on the fundamental and implicit schemes. A higher order perfectly matched layer scheme is modified to terminate plasma domains. Numerical experiments are employed to illustrate the algorithm. From results it behaviors considerable performance in the aspects of accuracy, memory and absorption. Meanwhile, the time step can be enlarged according to the relaxed stability condition, which significantly improves efficiency.
