| Abstract: | The generation and propagation of Magnetostatic Forward Volume Waves(MSFVWs)in the Bi- doped YIG film under transversely nonuniform bias magnetic fields are analyzed using the variational approach. The diffraction efficiency of the guided optical waves with the MSFVWs is calculated and the theoretical results are in good agreement with the experimental data in the excitation range of linear MSFVWs.This analytic procedure may be applied to the optimization design for the linear MSFVW-based Bragg cells. |
