基于对相位耦合机制的旁路微带线结构中类量子干涉行为的理论研究。通过格林函数框架下的界面响应理论,解析、计算了该结构中的波传播特性,得出了3种具有代表性的类量子干涉现象:两个谐振结构之间的干涉增强导致的反射加强,两者的干涉相消导致的类电磁诱导透明行为,以及谐振结构与波导结构的干涉导致的类Fano共振现象。引入相位耦合机制为结构中的波传播特性提供了更加丰富的调控手段,有望设计成新型调控器件。
The paper theoretically demonstrates the classical analog of quantum interference effects in microstrip system containing phase-coupled side-branch components.By employing the Interface Response Theory which is in the framework of Green's function method,the propagation properties of the system are analytically obtained,and three typical phenomena are presented.The first is the enhancement of reflection resulting from the constructive interference between two resonances;the second is the analogous electromagnetically induced transparency effect due to the destructive interference;and the third is the analogous Fano resonance based on the interference between resonances and propagating waves.The introduction of phase-coupling mechanism provides us great flexibility in manipulating wave propagations,which may pave a way to novel devices.
