采用一维量子波导理论研究了带有一个Stub的三臂环中的透射系数和持续电流.探讨了透射系数和持续电流对环的尺寸和Stub长度的依赖关系.结果发现:当kl1取某一个固定值,满足kL＝nπ时,系统出现反共振现象.而且适当地调节系统的参数,可以出现明显的Fano共振现象.

Based on quantum waveguide theory, the transmission coefficient and the persistent currents in a multi-arm ring with a stub are investigated theoretically. The numerical results examine the dependence of the transmission coefficient and the persistent currents on the size of the ring and the length of the stub. The studies show that the transmission become anti-resonant when kL equal to nπ for some fixed value of kl1. Also Fano resonance may appear if one chooses the systematic parameters reasonably.
