Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The process of Cherenkov electromagnetic field excitation by а laser pulse in the dielectric waveguide is investigated. Nonlinear electric polarization in an isotropic dielectric medium and, accordingly, polarization charges and
currents induced by ponderomotive force of the laser pulse are determined. Spatial structure of the excited wakefield
in a dielectric waveguide is obtained and investigated. It is shown, that the wakefield consists of polarization potential electric field, caused by the nonlinear polarization of medium, and a set of eigen electromagnetic waves of the
dielectric waveguide. |
