CST阵中单元的边界条件

因为是宽带天线,所以想用时域算法。仿真阵列情况,需要设置周期性边界条件。
但是:
1、用unit cell会提示“Unit cell boundary condition is not supported by transient solver”。
2、用periodic边界又找不到间距设置。好像以自动产生的边界盒子为边界了,我的距离应该比这个大很多啊。
而且不改的话会有两个Warning:
Only straight metal edges on the boundaries are considered for the automatic decoupling plane.
Metal was found on the boundaries when searching for decoupling planes. Please consider increasing the distance between the structure and the boundaries.
请问unit cell和periodic哪个合适呢?用前者求解器怎么设置呢?用后者单元间距怎么设置呢?谢谢

你带宽多少?最好上模型
UC边界只有F求解器支持,要仿宽带是比较困难,得分段仿
一般来说UC边界适合算无穷大阵列,典型的像FSS
T适合算有限大的
