摘要：
We obtained the exact solutions of the PT symmetric potential V(x) = A[sech(?x) + i tanh(?x)] and found that this system has no bound-state. The PT symmetric potential was first studied in this article, and the handedness effect is shown from reflection coefficients. As the asymptotically non-vanishing imaginary potential component, when the direction of the incident wave is opposite, the transmission coefficient will emerge a complex phase factor.
