Description
It is of a special interest to calculate the radial and longitudinal components of polarization forces for charged particles channeling in tubes (capillaries, pores in the solid films, nanotubes). But dielectrics, as a rule, obey different reaction on the external vortex or potential electromagnetic fields. The polarization properties of homogeneous media described with the help of vortex and potential dielectric susceptibilities, which are generally speaking not coincide. In a case of non- homogeneous media taking into account of this difference seems to be perfectly inevitable. The linearity of Maxwell equations makes it possible the independent consideration of two mentioned kinds of field. The calculation of potential polarization fields as well as the corresponding forces was performed in a number of works, in opposite to what concerns the vortex fields. The density of electrical currents produced by both polarization and external charges should also be subdivided into vortex and potential components. We emphasize that point charge generate as the potential current as well the vortex one. Both the currents are delocalized. In present work we consider more in detail the influence of mentioned delocalization on the radiation effects in tubes.
