Non-Stationarity of Electromagnetic Waves Caused by the Movement of a Medium Boundary

5.1  Transformation of an Electromagnetic Wave by a Uniformly Moving Boundary of a Medium

Medium movement as a whole—movement of medium parameters, movement of a medium boundary together with movement of a medium or without it—leads to various non-stationary phenomena. Apart from the classical uniform movement of a medium or its boundaries, other forms of movement are of interest [1, 2]. Rotational movement has been investigated most often. It leads to the scattering [3, 4, 5, 6, 7, 8, 9] and amplification [10, 11] of electromagnetic waves and to the appearance of peculiar ponderomotive effects [12, 13]. The modulation and spectral transformation of ...
