摘要
椭球微粒是电磁波非线性介质的典型微观结构，了解椭球微粒的极化特性，是研究光、微波和毫米波非线性传播的基础。本文从特殊单轴椭球微粒出发，将其非线性电极化率的分析推广到一般椭球微粒，得到具有普遍意义的椭球电极化率张量的一般表达式，并以此为基础分析了悬浮椭球与场的相互作用。
Microellipsoid is the typical micro-structure for nonlinear media of electromagnetic waves travelling. Its polarization characteristic is the basis for the analysis of light, microwave andmillimeter wave nonlinear propagation. General expression of polarizability for generalmicroellipsoid is deduced on the base of symmetrical cylindrical microellipsoids. The interactionbetween suspended microellipsoid and electric field is analyzed.
