【摘要】 本文推导了磁化球形铁氧体的张量磁导率[μ(r,θ,φ)]表示式。对使用球形铁氧体的新颖波导环行器进行了模式研究,结果与文献[1]所给实验值符合。并在求得对应于每一本征激励的电磁场值后,讨论了对两种圆极化本征激励的谐振频率的分裂。更多还原

【Abstract】 In this short paper the permeability tensor expression [μ(r, θ, φ)] of a magnetized ferrite sphere is derived. Operation modes of the novel waveguide circulator with a ferrile sphere are also investigated and agreement between theory values of resonance frequencies and experiment values in [1] is obtained. After the RF fields corresponding to each of the eigen-excitations are derived, the resonance frequency splits for the two rotational phase eigen-excitations are discussed finally.更多还原
