Unidirectional Reflectionless Propagation in Plasmonic Waveguide System Based on Phase Coupling Between Two Stub Resonators
A scheme on 6.15 unidirectional reflectionless propagation is theoretically investigated in a plasmonic waveguide system which consists of two metal-insulator-metal (MIM) stub resonators side coupled to an MIM plasmonic waveguide.By appropriately tuning the phase difference between two stub resonators, unidirectional reflectionless propagation at e
