一些數值方法在鐵氧磁體靜磁共鳴器

Abstract

本論文探討有關一些數值方法在靜磁振動光譜在小的鐵氧磁體圓盤共鳴器。這個能量光譜問題可被Walker equation所描述，其中方程式由雙曲線型在鐵氧磁體改變到橢圓型在絕緣體。此外，藉著解數個特徵值問題我們可以得到這個磁導率和磁場在鐵氧磁體。我們因此有靜磁的位能分佈在這鐵氧磁體。

Numerical methods for the magnetostatic oscillating spectrum in small ferrite disk resonators are presented. The energy spectral problem is described by the Walker equation that changes its type from hyperbolic in the ferrite to elliptic in the dielectric. Moreover, by solving the eigenvalue problem, we obtain the permeability and the magnetic field of the ferrite. We thus have MS-potential distribution of the ferrite
