摘要

An electromagnetically induced transparency (EIT) in metamaterial resonator with two bright modes and one dark mode at the terahertz (THz) band is numerically and experimentally demonstrated.Different from two kinds of the traditional passive modulations,our design can realize the passive modulation of EIT phenomenon by adding aoother bright mode resonator.Simulated and experimental results show that the transmission peak varies for incident THz waves with different polarization directions due to its asymmetric structure,which provides a novel way to realize high efficiency switch and modulation.
