【摘要】 本文推导了旋磁介质加载矩形波导特征方程的一般式,从而得到了旋磁介质加载的主模特征方程,计算了同向或异向磁化状态中的介质片厚、外加磁场以及饱和磁化强度、介质参数之间的关系曲线,给出了在给定介质片厚情况下满足局部均匀场条件时的外加磁场与频率的关系。最后讨论了高次模对均匀场的影响。更多还原

【Abstract】 General formula of characteristic equation for rectangular waveguide loaded by gyromagnetic dielectric slabs is derived and characteristic equation of fundamental mode is obtained in this paper.Relation curves among the thickness of electronic slab,direct magnetic field applied,saturation magnetization and di- electric constant are computed in the case of different direction magnetization.Frequency relation of the di- rect magnetic field applied,which satisfies the partial uniform condition,is given when the thickness of the di- electric slab is specified.The effeetion of the higher order modes on the uniform field is discussed.更多还原
