From: Goos–Hänchen shift of inelastically scattered spin-wave beams and cascade nonlinear magnon processes
Dependencies of the lateral shifts \(\Delta {X_{i}}\) along the interface of reflected and inelastically scattered beams for different angles of SW beam incidence (\(\theta\)), and edge SWs frequencies (\(\nu\)), and wavevector sign \(\kappa >0\) and \(\kappa <0\). On the left side of the black dashed line (subfigures (a,b)), lateral shifts of the scattered beams are presented in the case of edge mode with \(\kappa > 0\). (a) Lateral shifts of the beams generated in SSP, and (b) in CP for all simulated angles of SW beam incidence. To the right of the black dashed line (subfigures (c)–(f)) the lateral shifts of the edge modes with \(\kappa < 0\). The blue triangles show the lateral shifts of the elastically reflected beams and purple squares show the results corresponding to CP. The empty squares indicate the frequencies with the enhanced magnitude of \(|\Delta X_+|\).
