“…Expressions ( 13)-( 16) are derived here from the qualitative description of the phenomenon in terms of equivalent photons and from fundamental conservation laws. Furthermore, these results coincide with the results of the direct calculation based on Maxwell's equations in the vacuum ultraviolet and X-ray ranges for the calculation of radiation from a single charged particle (theory of diffraction radiation in [12] and the theory of Smith-Purcell radiation [9]) and for the calculation of radiation from bunches of particles with both a uniform distribution of particles [13][14][15] and a Gaussian distribution [16]. The dependence of the radiation field of type ( 11) also occurs for ideally conducting targets, i.e., in the long-wavelength part of the spectrum (see [17,18]).…”

“…In this case, radiation can be more intense if the center of the bunch moves very close to the surface. Such radiation can be described more strictly as done in [16]. However, for the qualitative consideration of the effect, it is sufficient to limit the distribution function:…”

It has been shown that polarization radiation of charged particle beams generally includes an incoherent form factor caused by a finite transverse size of a beam. Consequently, a widespread opinion that the form factor characterizes only coherent radiation of charge particle bunches is generally invalid. The reason for the existence of incoherent form factor is the interaction of charged particles with the target edge in the direction perpendicular to their trajectory. The incoherent form factor exists for diffraction radiation, Smith-Purcell radiation, and other types of polarization radiation in the case of transversely limited targets: transition radiation, parametric X-ray radiation, and Cherenkov radiation. It has been shown that the difference of the incoherent form factor from unity increases with a decrease in the ratio of the impact parameter to the transverse size of the bunch. Furthermore, it has been shown that the transverse part of the coherent form factor differs from unity to the same extent as the incoherent form factor.
