Numerical solution of the time-dependent Schrödinger equation for open system structures has been impeded by the difficulty in handing open-system boundary conditions. This paper presents a new numerical method for time-dependent Schrödinger equation and a boundary condition method to simulate the interaction with ideal particle reservoirs at the structure boundaries.
