metadata.name: dc.description.abstract
metadata.value: The problem of the electromagnetic field of a charge moving along the cylindrical waveguide
  axis is considered. The charge flies from the homogeneously filled area to the area composed of a
  dielectric layer and a channel. The solution is performed by representing the electromagnetic field
  in each waveguide area as a sum of known “forced” field (the source field in an infinite regular
  waveguide) and a “free” field conditioned by the transverse boundary influence. The free field
  is written in the form of eigenfunction expansion for corresponding waveguide area. Shown that
  the problem is reduced to solving an infinite system of linear algebraic equations for the free field
  mode amplitude. Expressions for the components of the free field “cherenkov” part are obtained
  using the methods of complex variable theory. It is shown that there is a compensation effect
  between cherenkov part of the free filed and wakefield. It leads to the decreasing of the number of
  the “total Cherenkov field” modes with increasing distance from the charge. The generation area
  border for each cherenkov mode is determined by the its group velocity. The wakefield formation
  process is demonstrated using the original numerical algorithm. Refs 17. Figs 2.
