Description
The results of theoretical investigation of the spectral and angular distributions of the radiation generated by a charged particle crossing a ball of dispersive material in vacuum, are presented. Previously, in the case of a non-dispersive dielectric ball it was shown that strong peaks appear in the spectral distribution of the radiation intensity for certain values of the problem parameters. In this work we show that by choosing the dispersion law it is possible to achieve the generation of powerful radiation not in narrow bands, but over a fairly wide frequency range.
The work was partially supported by the Science Committee of RA, in the frames of the research project № 21AG-1C069.
