摘要/Abstract

摘要：

通过给出交替隐式时域多分辨分析算法(ADI\|MRTD)公式, 用完全匹配层(PML)作为ADI\|MRTD算法的吸收边界条件, 将其应用到非对称共面波导（ACPW）及超宽带ACPW滤波器. 计算及实验结果表明, ADI\|MRTD算法与传统FDTD算法相比, 所需计算的网格数量减少, 节省了计算内存, 计算效率更高, 与FDTD计算结果及测量结果相符.

关键词: 交替隐式时域多分辨分析, 完全匹配层, 非对称共面波导, 滤波器

Abstract:

The authors presented alternating direction implicit multiresolution time\|domain (ADI-MRTD) formulation, and implemented perfect matched layer (PML) as absorbing boundary conditions of ADI\|MRTD method. The application of the ADI\|MRTD method to the calculations of asymmetrical coplanar waveguide (ACPW) and ultra\|wideband ACPW filter. The numerical and measured results show the advantages of ADI-MRTD over conventional FDTD method with respect to memory and mesh requirements and execution time, and the numerical result of ADI\|MRTD is in agreement with FDTD and measured result.

Key words: alternating direction implicit multiresolution time\, domain (ADI\, MRTD), perfect matched layer (PML), asymmetrical coplanar waveguide (ACPW), filter
