摘 要: 对无限大均匀线性各向同性介质中的均匀平面电磁波的场强,分别采用时域法和频域法进行了推导和分析.两种算法的数学本质和场强解析解的物理意义为:电场强度和磁场强度具有相同的空间相位和时间相位,并且电场强度垂直于磁场强度,它们与电磁波传播方向垂直.电场强度与磁场强度的振幅只相差一个比例因子. Field intensity is related to plane uniform electromagnetic wave which travels in linear iso- tropic uniform medium, while analytic algorithm can be classified into time and frequency domains. Its mathematical theory and physical meaning claims that electric and magnetic field intensities have the same space and time phases at perpendicular status. Both are perpendicular to the wave travelling direction. Amplitude of magnetic field divided by wave impedance is the amplitude of electric field.
