可极化球体的椭圆极化特性

Elliptic Polarization Characteristics of Polarizahle Sphere

电磁波的椭圆极化参数描述了电磁波的矢量特性。计算了在大地电磁场源作用下,均匀半空间中可极化高阻球体、不极化高阻球体、可极化低阻球体、不极化低阻球体的椭圆极化参数,分析对比了相同条件下可极化球体与不极化球体的剖面特性和断面特性。结果表明在相同条件下,极化球体具有明显异常的形态特征。

The vector characteristics of electromagnetic wave are described with elliptic polarization parameters of the electromagnetic waves. The elliptic polarization parameters of polarizable high resistive sphere, non-polarizing high resistive sphere, polarizable low resistive sphere and non-polarizing sphere in even hemispace are calculated under effect of magne-totelluric field source, profile and cross-sectional characteristics of polarizable sphere are analytically compared with that of the non-polarizing sphere under the same conditions. The result indicates that under the same conditions the polarizing sphere has obvious abnormal morphologic characteristics.
