Abstract
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.
