Despite spin-wave propagation in magnetic media being strongly anisotropic, we use axicons to excite spin-wave BesselGaussian beams and gradient-index lenses to focus spin waves in analogy to conventional optics with light in isotropic media. Moreover, we demonstrate spinwave Fourier optics using gradient-index lenses. Our results are valid for all three possible external magnetic field orientations and thus contribute to the growing field of spin-wave optics.en003621006519journal article
