Electromagnetically induced transparency is an optical phenomenon that is characterized by the elimination of the effect of a medium on a propagating beam of electromagnetic radiation in a specific frequency band. In this study, EIT was investigated at a proposed metamaterial with the dimensions milimeter and in the area of frequency of GHz. The computation results indicated that EIT with high transmission rate and high Q factor occurs in certain frequencies by breaking the symmetry in this structure. The sensitivity studies showed that the use of silver in the structure increases the quality factor so significantly that this quantity reaches 338 for gold and copper, while it reaches 677 for silver. In addition, By reducing the temperature, the transmission rate in the structure increases and reaches acceptable degree 98%. This structure can be an appropriate option for slow light usages, and it can be utilized for light amplification in microwave structures.
