This paper demonstrates the realization of the electromagnetically induced transparency (EIT)-like transmission in a metamaterial plasma waveguide with double side defects based on transmission lines. The waveguide with a single side defect works as a plasma resonator and the resonance wavelength is determined by the Fabry-Perot resonance of surface plasma. While in a waveguide with double side defects, a transmission peak appears between the two resonators frequencies because of the destructive interference between the resonance modes of the two resonators, which indicates a pronounced EIT phenomenon. The experiment results agree well with simulations in microwave frequencies.
