隧穿问题的数值算法

A Numerical Method for Tunneling

本文给出一种新的数值方法，用以计算隧道效应中的透射系数和相移。这个方法适用于任意形状的势垒，不仅可以计算透射系数，还可以计算透射波和反射波的相位。分析表明该方法具有很高的精度。

A new approach to tunneling is presented, This approach can be used to a potentialbarrier with arbitrary profile,It is able not only to calculate the transmission coefficient accurately,but also to calculate the transmission wave phase and the reflection wave phase。
