摘要
将基于Daubechies尺度函数的时域多分辨率分析(Muti-Resolution Time-Domain,MRTD)方法应用到色散介质的分析中.采用梯形递归卷积(Trapezoidal Recursive Convolution,TRC)方法,推导出了适合Drude-Lorentz模型的差分方程.通过对一维等离子体和金属铝板反射系数的仿真分析,证明了该方法的正确性和有效性.与基于辅助方程(Auxiliary Difference Equation,ADE)的MRTD方法相比,该方法可以有效地节约内存和计算时间,并且获得更高的计算精度.
The trapezoidal recursive convolution(TRC)method is incorporated into the muti-resolution time-domain(MRTD)to analyze the dispersive media.The formulations for the Drude-Lorentz media are derived and applied to calculate the reflection coefficients of plasma and aluminium.The numerical results show that,compared with the auxiliary difference equation(ADE)based MRTD,the proposed scheme can obtain more accurate results,while consumes less memory and CPU time.
