高精度迭代ADI-FDTD方法
High Accuracy Iterative ADI-FDTD Method
介绍了一种新的迭代交替方向隐式时域有限差分（ADI-FDTD）方法，该方法将近似ADI-FDTD方法的计算结果作为迭代初始值。相对于传统迭代方法，新的迭代方法只需较少的循环次数，便可得到较高的计算精度，计算效率得到了提高。文中采用数值算例证明了该方法的有效性，结果显示，新迭代ADI-FDTD方法的迭代次数可降低为传统迭代方法的1/4.
his paper presents a new iterative alternating-direction implicit finite-difference time-domain (ADI-FDTD) method, in which the initial value is calculated by an approximate ADI-FDTD method. Compared with the conventional iterative ADI-FDTD method, the accuracy of this new iterative method is improved even with small number of iterations. Such the computational efficiency of the new scheme is improved. Numerical example is used to demonstrate the effectiveness of this new scheme and the result shows that the number of iterations of new iteration scheme is only 1/4 times as that of conventional iterative method.
