Abstract
A new reliable numerical method is proposed for solving the two-state coupled equations with two linear potentials which intersect with opposite sign of slopes. The original coupling equations which suffer from a very rapid oscillation are transformed into a new form which gives ordinary sine and cosine solutions asymptotically. The amplitude and phase of the scattering matrix can be stably and accurately calculated.
