摘要 研究了束传播算法 ( BPM)中简单透明边界条件 ( STBC)和完全透明边界条件 ( CTBC)两种边界处理算法对计算结果精度的影响 .通过改进和综合两种边界条件算法 ,提出改进型透明边界算法 ( ITBC) .该边界算法相对于 STBC与 CTBC降低了计算精度对于传播步长的依赖性 ,提高了计算精度 ,改善了透明边界条件算法在 BPM中的稳定性 . It studied simple transparent boundary condition (STBC) and complete transparent boundary condition (CTBC) used in beam propagation method (BPM) and their effects on calculation accuracy.And authors proposed improved transparent boundary condition (ITBC) based on the two methods.Compared with the previous two methods (STBC and CTBC),this method decreases the dependency on propagation step,which improves the stability in BPM calculation.
