摘要：
An acoustic wave of a combined frequency (formed upon the superposition of the opposite acoustic waves of close frequencies) from a moving source generates electromagnetic waves of the same frequency with the amplitude increasing in the longitudinal direction. The problem is solved for the first time, assuming the absence of electric charges and neglecting the frequency dispersion. It is shown that the running acoustic wave is accompanied by weak electromagnetic waves. This effect may find new ;applications, in particular, in the space energetic.
