Abstract

Most targets made of industrial materials, used for the generation of Cherenkov radiation (ChR) have a refractive index n>1.4 in millimeter wavelength region. It is often a problem to get out the radiation from such cylindrical or flat targets because the angle of incidence of ChR on the outer surface of target is greater than the angle of total internal reflection. In this work we present the solution of this problem by the usage of the targets with predetermined dielectric properties, manufactured using 3-D printer. We demonstrate the emission of ChR in millimeter wavelength region from the such flat target with the refractive index n=1.37. Suggested technique allows us to fabricate targets with turned refractive index.
