同一个结构的周期性边界仿真存在差异

      老师您好,我在使用FDTD仿真金属超表面的透射率和反射率时发现,尽管模型XY方向都已经设置为周期性边界条件了,移动模型内部的金属结构位置,仿真结构存在明显的差异,这是为什么呢?这个问题有办法解决吗?

      您好,这里可能需要理解周期性边界的含义,它是指说仿真区域作为一个周期单元,周期性重复后的结果。那么可以看到你这里调整金属位置,其实对于周期单元来说已经改变了,所以结果肯定是会有变化的。详细说明可参考:https://optics.ansys.com/hc/en-us/articles/360034382734-Periodic-boundary-conditions-in-FDTD-and-MODE
