均匀平面波在无损耗媒质中传播时，平面波的电场与磁场的振幅之比等于媒质的本征阻抗，在理想介质中，阻抗为一正实数。因为电场、磁场方向始终不变，根据它们的值，利用MATLAB提供的实现动态轨迹.-Uniform plane wave propagation in the lossless medium, the plane wave of electric and magnetic fields is equal to the ratio of the amplitude of the intrinsic impedance of medium, in an ideal medium, impedance is a positive real number. Because the electric field, magnetic field direction remains unchanged, according to their values, provided by MATLAB dynamic trajectory.
