    We present a seismic modeling process based on one-way propagators to handle both reflection and refraction. In this process, vertical reflectivity, horizontal reflectivity, and velocity models are independently defined by their own coordinate positions in a so-called staggered grid. We introduce the concept of intermediate propagation, such as down-rightgoing and up-leftgoing wavefields, which are propagation modes between the horizontal and vertical reflectivity grid. In addition, internal multiples can also be generated by this process. This modeling method can serve as the engine for a controlled full wavefield inversion process. A numerical example is shown to demonstrate the validity of the proposed method.
