摘要: 通过引入椭球坐标系,求解满足给定边界条件的拉普拉斯方程,得出了带壳介质椭球内外的电势分布,从而进一步讨论了带壳椭球的等效介电常量.

关键词: 带壳介质椭球, 退极化因子, 电势分布, 等效介电常量

Abstract: Based on the ellipsoidal coordinate,the spacial distribution of electric potential of a coated ellipsoid in a matrix is investigated by solving the Laplace equations under the boundary conditions.Furthermore,the equivalent permittivity of a coated ellipsoid is obtained.

Key words: core-shell structured ellipsoids, depolarization factor, distribution of electric potential, equivalent permittivity
