چکیده
In this letter, a low numerical dispersion error single field (SF) hybrid implicit explicit (HIE) finite-difference time-domain (FDTD) method with artificial anisotropic (AA) parameters, AA-SF-HIE-FDTD for short, is proposed. Based on the formulas of SF-HIE-FDTD and by introducing electric anisotropy updated functions 3-D AA-SF-HIE FDTD can be obtained. The relation Fourier investigated. Compared conventional method, it found that AA parameters improve method.

Analysis and Compensation of Numerical Dispersion in the FDTD Method for Layered, Anisotropic Media
In this work, we investigate the effects of numerical dispersion in the finite-difference time-domain (FDTD) algorithm for layered, anisotropic media. We first derive numerical dispersion relations for diagonally anisotropic media (corresponding to an FDTD reference frame coinciding with the principal axes of a biaxial media). In addition, we incorporate the discretization effects on the reflec...
متن کاملAn Efficient Method to Reduce the Numerical Dispersion in the HIE-FDTD Scheme
A parameter optimized approach for reducing the numerical dispersion of the 3-D hybrid implicit-explicit finite-difference time-domain (HIE-FDTD) is presented in this letter. By adding a parameter into the HIE-FDTD formulas, the error of the numerical phase velocity can be controlled, causing the numerical dispersion to decrease significantly. The numerical stability and dispersion relation are...

This article shows the interfacial relation in electrodynamics shall be corrected in discrete grid form which can be seen as certain numerical dispersion beyond the usual bulk type. Furthermore we construct a lossy conductor model to illustrate how to simulate more general materials other than traditional PEC or simple dielectrics, by a new conformal FDTD method which main considers the effects...

In this paper, a recently improved SO-FDTD (shiftoperator finite difference time-domain) method is proposed and applied to the numerical analysis of the anisotropic magnetized plasma with arbitrary magnetic declination. By using the constitutive relation between polarized current density vector J and electric vector E and bringing the shift operators, the difference iteration equations of field...
