Spin waves (SWs) offer data transmission and data encoding capability in both amplitude and phase. Most of the works in this field are focused on developing novel and energy efficient control mechanisms of SW by different means such as voltage, current, light, heat etc., to use it in logic applications. However, this wave-based computation has the tremendous potential of parallel data processing. A multifrequency magnon network would allow parallel data processing within a single element. There are few reports about SW channeling in multiple paths in metallic ferromagnet. In this work, we experimentally demonstrated a novel multifrequency SW device that can operate at multiple frequencies simultaneously using the shape anisotropy of the magnonic film.
