Integrated optically-inspired wave-based processing is envisioned tooutperform digital architectures in specific tasks, such as image processingand speech recognition. In this view, spin-waves represent a promising routedue to their nanoscale wavelength in the GHz frequency range and richphenomenology. Here, we realize a versatile optically-inspired platform usingspin-waves, demonstrating the wavefront engineering, focusing, and robustinterference of spin-waves with nanoscale wavelength. In particular, we usemagnonic nanoantennas based on tailored spin-textures for launching spatiallyshaped coherent wavefronts, diffraction-limited spin-wave beams, and generatingrobust multi-beam interference patterns, which spatially extend for severaltimes the spin-wave wavelength. Furthermore, we show that intriguing features,such as resilience to back-reflection, naturally arise from the spin-wavenonreciprocity in synthetic antiferromagnets, preserving the high quality ofthe interference patterns from spurious counterpropagating modes. This workrepresents a fundamental step towards the realization of nanoscaleoptically-inspired devices based on spin-waves.
