Classical Analog of Quantum Interference Effects in Microstrip System Based on Phase-Coupling Mechanism

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.
