| Summary: | Title screen The properties of different types of radiation, such as diffraction and Cherenkov radiation, induced by an electromagnetic field of a relativistic electron in optical fibers were calculated by Artru and Ray (2013). These authors have showed a difference of the considered radiation from the traditional radiation mechanisms, such as transition and diffraction radiation. In this paper we present the results of experimental investigations of this phenomenon in millimeter wavelength region. The spectral characteristics and radiation yield depending on the impact-parameter of fibers relative to the electron beam were investigated and compared with backward diffraction radiation for similar conditions. The influence of a fiber curvature on the generated radiation transmission in agreement with theoretical prediction was shown. The role of evanescent waves in the radiation generation and transport in fibers was experimentally investigated using the millimeter wavelength emitter.
