摘要
讨论了一维非均匀介质中透射电磁波的振幅和传播速度。当选z坐标轴沿介质连续变化的方向时 ,在一般入射角度下 ,介质内透射电磁波电场振幅的Etx和Ety与z坐标无关 ,仅Etz与z坐标有关 ;透射电磁波的群速和相速相等 ,都为 1(z) μ(z)。
In this article the amplitudes and velocities of transmitting electromagnetic waves in inhomogeneous media of one-dimension are discussed.As we let z axis of cartesian coordinates be the inhomogeneous dimension of the media,in arbitrary angle of incidence,the amplitudes E tx and E ty are independent of coordinate axes,the amplitude E tz is dependent of z axis.The group velocity of transmitting waves is equal to phase one,which is dependent of z axis.
