在柱坐标系下，提出了一种基于Yee网格的虚距光束传输方法（ID-YM-BPM），该方法严格考虑了本征模场的模数。ID-YM-BPM在空间网格尺寸方面具有二阶精度。对分段包层光纤进行了分析，结果与其它方法吻合较好。
An imaginary‐distance beam‐propagation method based on Yee's mesh (ID‐YM‐BPM) is developed in cylindrical coordinates, in which the mode number of the eigenmode field is strictly considered. The ID‐YM‐BPM is second‐order accurate with respect to the spatial mesh size. A segmented cladding fiber is analyzed, showing good agreement with other methods.
