Abstract: A novel finite-difference time-domain(FDTD) method for anisotropic magnetized plasma is derived with piecewise linear approximation and recursive convolutions of current density J and electric field E.J and E employ a piecewise linear approximation,respectively.High efficiency and accuracy of the method are confirmed with reflection and transmission coefficients through a collisional magnetized plasma slab with propagation direction parallel to biasing field.Compared with frequency domain analytic results,good agreement is observed.The proposed method shows higher efficiency and accuracy than current density convolution(JEC-FDTD) and piecewise linear current density recursive convolution(PLCDRC-FDTD) approaches.In addition,Faraday rotation effect is demonstrated.
