The field of Magnonics, which utilizes magnons, the quanta of spin waves, for energy-efficient data processing, has made significant advancements through the application of inverse design. A universal magnonics processor has been developed, utilizing a 7x7 array of independent current loops to generate local inhomogeneous magnetic fields, thereby scattering spin waves in an Yttrium-Iron-Garnet film to achieve various functionalities. In this system, binary data ('0' and '1') is encoded in the spin-wave amplitude, and by making use of the nonlinearity of spin waves and applying the inverse-design process, logic gates including NOT, OR, NOR, AND, NAND, and a half-adder have been successfully created.
