Abstract

In this paper we show that the Cerenkov radiation in artificial dielectric (metamaterial) noticeably increases Smith-Purcell radiation (SPR) intensity from the metamaterial grating if the two radiation condition is properly matched. We compare the radiated field intensity from lamellar metal grating and metamaterial grating and found that radiated field intensity of metamaterial grating is more intense than radiated field intensity of lamellar grating.
