Abstract: THz (Terahertz) radiation sources are an important research topic in THz science and technology. Novel THz radiation using double negative metamaterials (DNMs) and electron beam bunches is a promising candidate. In this review paper, we first introduce THz metamaterials, especially DNMs, including the design, fabrication and testing. Then we present our research progress on the enhanced THz radiation based on DNMs using single and multiple charged particles. Finally, we discuss the challenges in metamaterials and associated radiations. The research presented here offers theoretical and experimental foundations for developing new THz radiation sources.
Keywords: Double negative metamaterials, THz metamaterials, THz radiation, THz sources.
