  Spin waves (SW) can induce rich domain wall (DW) motion in a
perpendicular-magnetic anisotropy nanostrip. In-plane magnetization tilt angle
resulting from the fluctuation of the effective field of the magnetization
response in the DW region plays an essential role in the dynamics of SW
interacting with a DW. We performed simulation and found that the transmission
ratio of the propagating SW across the DW depends strongly on the tilt angle in
the low-frequency regime. The material parameters and the geometrical
configuration can be fine-tuned for practical devices.
