| Abstract: | In this paper,we studied the problem of persistent current and transmission of two contacted Aharonov-Bohm Rings coupled to extent leads,and give the analytical solution.The conditions of observing persistent current,zero and perfect transmission are discussed,and the Fano resonance is studied. |
