Abstract
Smith-Purcell and diffraction radiation were investigated. These types of radiation
appear when a charged particle moves close to a conducting target. Spectral and angular distribution of diffraction radiation from a non-periodic chain of spheres is obtained analytically; local field effects are discussed. Analytical expression for the distribution of Smith-Purcell radiation from the periodic chain of spheres is obtained as well. For the first time it has been shown, that Smith-Purcell radiation for such a system is distributed over the cone. The results are investigated for the particles of different sizes, dielectric and metal, and for both ultrarelativistic and nonrelativistic cases.
