Multiple truly topological unidirectional surface magnetoplasmons at terahertz frequencies

Shengquan Fan, Tianjing Guo, Binbin Zhou +7

Unidirectional propagation based on surface magnetoplasmons (SMPs) has recently been realized at the interface of magnetized semiconductors. However, usually SMPs lose their unidir…

Robust multimode interference and conversion in topological unidirectional surface magnetoplasmons

Chao Liu, Ziyang Zhao, Tianjing Guo +6

We have theoretically investigated surface magnetoplasmons (SMPs) in a yttrium-iron-garnet (YIG) sandwiched waveguide. The dispersion demonstated that this waveguide can support to…
