L. R. Arnaut

摘要:

利用自由随机电磁波的角平面波谱的TE/TM分解和匹配边界条件,我们导出了存在半无限各向同性介质时矢量电场的能量密度的概率密度函数。良好的电导体和一个无损的介电半空间的计算和结果的理论分析说明。的介电常数和电导率的强度,随机极化,统计分布和标准偏差的字段的影响进行了调查,无论是入射加反射场和折射场。发现外折射导致随机场波动的压缩。

英文摘要:

Using a TE/TM decomposition for an angular plane-wave spectrum of free random electromagnetic waves and matched boundary conditions, we derive the probability density function for the energy density of the vector electric field in the presence of a semi-infinite isotropic medium. The theoretical analysis is illustrated with calculations and results for good electric conductors and for a lossless dielectric half-space. The influence of the permittivity and conductivity on the intensity, random polarization, statistical distribution and standard deviation of the field is investigated, both for incident plus reflected fields and for refracted fields. External refraction is found to result in compression of the fluctuations of the random field.
