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