By using bpm , the problem is reduced from a second - order boundary value problem requiring iteration or eigenvalue analysis to a first - order initial - value problem that can be solved by simple " integration " along the propagation direction 和其他模擬方法相比, bpm將二階邊值問題簡化為一階初值問題,減小了計算的復(fù)雜性,縮短了計算時間,降低了對計算機硬件的要求。
