Using plasmonic devices, by converting incoming light into surface plasmon polaritons on the border between metal and dielectric at the same frequency, faster signal processing and light transmission is possible in the very compact space. In this paper we tried to design a new structure for slow light creation based on plasmonic induced transparency in a circular metal-dielectric-metal resonator. Length of the proposed plasmonic system is about 600 nm and the radius of the ring is equal to 5.5 micrometers. First we used gold as the metal of the structure then changed it to silver. In both cases, the dielectric material is poly-methyl meta-acrylic, the pump wavelength is 1550 nm and the signal wavelength is 860 nm. Simulation results show that in the first case, where the metal is gold, slow light features are much better in comparison with the second case, where the metal is silver.
