| Abstract: | A new algorithm for calculating tunneling problems is presented. A series of rectangular potential barriers are substituted for a given potential barrier. Under this approximative condition, the transfer matrix and the transmission coefficient are obtained by the solution of Schrdinger equation. This algorithm is applied to potential barriers with an arbitrary profile. Numerical analysis shows that this algorithm gives very high accuracy. |
