本文从麦克斯韦方程出发,求出有损耗的长椭圆旋转介质球中一个同焦点的小的长椭圆旋转形半波振子发射天线上的电流分布和其输入阻抗,以及它在有损耗的介质球中和外部自由空间中所产生的场。A prolate spheroidal dipole antenna embedded in a larger dielectric confocal prolate spheroid with finite conductivity is analized as a boundary value problem in electromagnetic theory; the expressions for the fields, antenna current distribution and input impedance are obtained.
