[Invited] Plasmon induced transparency in terahertz metamaterials

摘要

Metamaterials that reveal fascinating and unique resonant properties allow for adequate control of electromagnetic waves at will. Recently, considerable studies have shown that plasmon induced transparency (PIT) effect can be realized by metamaterials via destructive interference between different resonance modes. Within the sharp transparency window, the high dispersion of the medium may lead to remarkable slow light phenomena and enhanced nonlinear effect. Here, we summarize research on terahertz PIT effect with various functionalities.
