一种计算微波电路的并行算法──FDTD-Diakoptics

A Parallel Algorithm for Microwave Circuit Simulations

FDTD-Diakoptics将复杂的微波电路分割为若干较为简单的子电路，使用有限时域差分方法（FDTD）独立求解每个子电路的时域特性，使用并行算法连接各子电路，最终得到整个电路的特性本方法适用于结构复杂、规模较大的微波电路的分析设计，与整个电路使用FDTD进行设计研究的方法比较，本算法在保证相同数值精度的条件下可以提高计算效率五倍左右。

In FDTD-Diakoptics , a complex microwve circuit is partitioned into several simple sub-circuits. Each subcircuit is analyzed by finite-difference time-domin (FDTD) method independently,and a parallcl algorithm is applied to cascade all the sub-circuits together. The metdod in this paper is Particularly suitable to the analysis and design of the geometrically complex structures and the clectrically large circuits. With the sarne computational precision, the efficiency is improvedapproximately five times by using the proha apprcach compared to the method using are to analyze the circuit entirely.Therefore the method prasented in this paper is very useful.
