摘要
结合运动介质本构关系,运用并矢代数方法,求解运动介质中电磁场的色散关系.结果表明,波数k与波频ω之间仍然保持线性关系,其比例系数决定于波传播方向k与介质运动方向v之间的夹角θ、参考系之间的相对运动速度v以及静止介质折射率n′的大小.
The dispersion relation in the moving medium is solved by use of the dyadic algebraic method and combining with the constitutive relation of the moving medium.The results show that the wave number is directly proportional to the wave frequency, and the proportionality factor is determined by angle θ between the wave propagation direction k and the medium moving direction v ,the relative velocity between the reference frames and the refractive index in the static medium.
