In this report, the experimental investigation of the interaction of relativistic electron beam electromagnetic field with a metamaterial is presented. Used metamaterial target represents the right triangular prism. The unit cell of studied target consists of split-ring resonator (SRR) and wire. Size of the unit cell is 3 mm. The measurements were conducted in millimeter wavelength range in far field zone on relativistic electron beam with energy of 6 MeV. The measured angular dependencies show that the radiation, generated by the electron bunches moving near the target, is observed in the backward semi-sphere. In approximation of scalar refractive index, obtained result can be interpreted as a reversed Cherenkov radiation.
