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，故具有广泛的应用前景
FDTD-Diakoptics divides the complex microwave circuit into several simple sub-circuits, solves the time-domain characteristic of each sub-circuit independently by finite difference time-domain method (FDTD), uses the parallel algorithm to connect the sub-circuits and finally obtains the characteristics of the whole circuit The method is suitable for the analysis and design of microwave circuit with complex structure and large scale. Compared with the method of designing and studying the whole circuit using FDTD, this algorithm can improve the computational efficiency about five times under the same numerical precision, The application prospects
