摘要：
The phenomenon of electromagnetic induced transparency (FIT) based on graphene in microwave band has seldom been studied due to its shortcomings in frequency modulation in this band. However, based on the excellent tunability of graphene, EIT with adjustable amplitude in microwave frequency band is still applicable. In this letter, a tunable EIT structure based on graphene in microwave band has been proposed, which has a transparent window at 1.6 GHz with a tunable transparency from about 40% to 85% adjusting the sheet resistance of graphene. The result shows that, the proposed structure has excellent adjustability and switching characteristics.
