Optimized higher order 3-D (2,4) FDTD scheme for isotropic dispersion in plasma

In this paper, an optimized higher order (2,4) 3-dimensional finite-difference time-domain (FDTD) method is applied in plasma. The optimized scheme uses the scaling factors and weighted sum of the standard FDTD method (Yee's scheme) and the standard (2,4) higher order FDTD method (H(2,4)) propo...

Zusammenfassung:In this paper, an optimized higher order (2,4) 3-dimensional finite-difference time-domain (FDTD) method is applied in plasma. The optimized scheme uses the scaling factors and weighted sum of the standard FDTD method (Yee's scheme) and the standard (2,4) higher order FDTD method (H(2,4)) proposed by Fang. The proposed scheme improves performance of phase and attenuation constant error over propagation angle without additional computational complexity compared with H(2,4). The maximum phase constant error of the proposed scheme is reduced by 99.998% of the H(2,4)'s error.
