摘要 推导了采用不同差分格式求解时域磁场积分方程的隐式算法表达式,将不同差分格式的电场和磁场积分方程相结合,建立了9种混合时域积分方程。采用不同入射信号形式分别对金属球体、导弹缩比模型进行仿真,分析了3种(电、磁、混合)积分方程不同差分形式隐式算法的性能。通过与球体散射数据的解析解以及导弹模型暗室测量数据和频域结果的逆傅立叶变换数据相比较验证方法的有效性。 Implicit expressions are deduced from magnetic field integral equation using different kinds of finite differences, and a unified equation is proposed. Nine integral equations are obtained through combine electric field integral equation with magnetic field integral equation with different kinds of finite differences. Comparisons for different kinds of differences are presented to illustrate validities for improving late-time stability through simulation for a PEC sphere and a scalemodel of missile by using different kinds of incident pulse.
