N2 - We consider electromagnetic radiation of a charge which moves in a volume structure consisting of thin parallel wires and having small period. The structure is described by the permittivity tensor. The charge velocity is directed perpendicularly to the wires. Analytical and numerical investigations are performed for the case of point charge. Some unusual properties of radiation are noted. In particular, it is shown that radiation propagates along the wires and concentrates nearby certain “rays” behind the charge. The wave field doesn’t decrease with increase in distance along these “rays”. The cases of Gaussian and rectangular bunches with negligible thickness are considered as well. Prospects of use of structure under consideration for diagnostics of bunches are noted.
