使用表面磁导率法得到斜向磁化金属/电介质/钇铁石榴石(YIG)/钆镓石榴石(GGG)/金属多层电介质结构中静磁波的传播方程。通过分析静磁正向体波(MSFVW)和静磁反向体波(MSBVW)延迟特性设计出级联MSFVW-MSBVW延迟线系统,该系统通过调节MSBVW延迟线激发场角起到控制非色散延迟时间的作用。数值计算得到一个近500MHz的非色散延迟带宽,延迟时间具有156.4～186.6ns/cm的可调范围。
Using the surface permeability method, the propagation equation of magnetostatic wave in oblique magnetized metal / dielectric / yttrium iron garnet (YIG) / gadolinium gallium garnet (GGG) / metal multilayer dielectric structure is obtained. The cascaded MSFVW-MSBVW delay line system is designed by analyzing the delay characteristics of MSFVW and MSBVW. The system controls the non-dispersion delay by adjusting the MSBVW delay line excitation field angle The role of time. The numerical calculation results in a non-dispersion delay bandwidth of nearly 500MHz with a delay time of 156.4 ~ 186.6ns / cm.
