Abstrakt

The development of fast magnonic information-processing devices requires operating with short spin-wave pulses, but, the shorter the pulses, the more affected they are by information loss due to broadening and dispersion. The capability of engineering spin-wave pulses and controlling their propagation could solve this problem. Here, we provide a method to generate linear spin-wave pulses with a desired spatial-temporal profile in magnonic waveguides based on inverse design. As relevant examples, we theoretically predict that both rectangular and self-compressing spin-wave pulses can be generated in state-of-the-art waveguides with fidelities ≳96% using narrow stripline antennas. The method requires minimal computational overhead and is universal, i.e., it applies to arbitrary targeted pulse shapes, type of waves (exchange or dipolar), waveguide materials, and waveguide geometries. It can also be extended to more complex magnonic structures. Our results could lead to the utilization of large-scale magnonic circuits for classical and quantum information processing.
