Abstract

A new msthod of measurements of all complex permeability tensor components of microwave ferrites, using one cylindrical ferrite sample is presented. Two dielectric ring resonators having the same heights and internal diameters but different external diameters operating on HE± 111 and H011 modes respectively are applied for measurements. Permeability tensor components are computed from the measured resonant frequencies and Q-factors of these resonators with and within ferrite sample. Computations are based on the exact eigenvalue equations for this modes.

用一个圆柱形铁氧体样品测量微波铁氧体所有复磁导率张量分量的新方法
提出了一种利用一个圆柱形铁氧体样品测量微波铁氧体所有复磁导率张量分量的新方法。采用两个高度和内径相同但外径不同的介电环形谐振器,分别工作在HE±111和H011模式下进行测量。磁导率张量分量由测量的谐振频率和磁导率因子计算得到。计算是基于该模态的精确特征值方程。
