dc.description.abstract A phenomenon of negative refraction of dipole-exchange spin waves (DESWs) was demonstrated by micromagnetic modeling, based on the fact that the DESWs' dispersion is anisotropic according to the relative orientation of the DESW propagation direction with respect to the orientation of local static magnetizations. Using this anisotropic dispersion behavior, the negative refraction of the DESWs was reproduced through a magnetic twin interface in a geometrically restricted medium of cubic in-plane anisotropy. This work verifies that the negative refraction of electromagnetic waves can also occur for DESWs propagating in restricted geometry through a specially designed magnetic interface. ko
