Abstract

The amplification of weak electromagnetic wave in the surface Cherenkov process when strongly magnetised electron beam (one dimensional process) propagates above a dielectric waveguides is thoroughly investigated by J. E. Walsh and co-authors (see e. g. [1]). Lately a new fundamentally incorrect conception has been developed [2,3] proving that both amplification and all other stimulated phenomena for unmagnetised electron beam propagating in vacuum cannot take place.
