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…
Aligning Few-Step Diffusion Models with Dense Reward Difference Learning
Ziyi Zhang, Li Shen, Sen Zhang +6
Few-step diffusion models enable efficient high-resolution image synthesis but struggle to align with specific downstream objectives due to limitations of existing reinforcement le…
Broadband energy squeezing and tunneling based on unidirectional modes
Lujun Hong, Yazhou Wang, Yun Shen +4
Energy squeezing attracts many attentions for its potential applications in electromagnetic (EM) energy harvesting and optical communication. However, due to the Fabry-Perot resona…
