| 摘 要： | 实现了基于Daubechies紧支集尺度函数的时域多分辨分析(MRTD)算法的各向异性理想匹配层(APML)吸收边界条件，并将其应用到平面光波导的仿真和分析中。验证结果表明，APML吸收层性能主要由其层数和计算空间步长所决定。与传统的时域有限差分(FDTD)法相比，基于高阶消失矩Daubechies尺度函数的MRTD法可以提高吸收层性能。

| Abstract: | The anisotropic perfectly matched layer(APML) absorbing boundary condition for the multiresolution time domain(MRTD) method based on Daubechies compactly supported scaling functions was implemented and applied to the simulation of the planner waveguide.The results show that the performance of APML is dependent on the thickness of the APML medium and the size of the computational cell.Compared with conventional FDTD method,the MRTD method based on Daubechies scaling functions with the higher order of vanishing moments could improve the performance of APML. |
