【 摘 要 】

We investigate the electromagnetic fields and the radiation intensity for a charged particle moving along an arbitrary closed orbit around a dielectric cylinder immersed into a homogeneous medium. These results generalize our previous research in the special case of a circular orbit. For the latter geometry it has been shown that under certain conditions strong narrow peaks appear in the angular distribution of the radiation intensity in the exterior medium. We discuss the influence of the trajectory shift from the circular one on the characteristics of the peaks.
