dc.description.abstractRadiation from electron bunches is usually used for diagnostics of its transverse sizes in accelerators and colliders including FELs and synchrotron injectors [1,2]. However, the methods of diagnostics continue to improve. There are some ideas on single-short diagnostics, or non-destructive diagnostics, or using new types of targets, among which metamaterials and photonic crystals seem to be attractive. In this report we suggest using incoherent transition radiation from two-periodical targets in order to defi ne transversal sizes of the bunch. Usually the diagnostics is reduced to comparison the measured data to the theoretical one, which take in account the coherent eff ects [3,4]. The generally accepted approach to take into account coherence from electron bunches consists in multiplying the radiation intensity from one particle by the bunch form-factor, which takes into account its size, shape, and distribution of electrons. We show that in polarization radiation for a wide class of structures, such as photonic crystals and metasurfaces, this approach is incorrect [5,6].
