Robust Wireless Power Transfer via Topological Dimer Chain

Wireless power transfer (WPT) applications are becoming increasingly widespread, with the popularity of various electronic products and electric vehicles. In this paper, we proposed a topological dimer chain WPT system which can transfer power over a long distance with coils in a chain. At the same time, the unique topological edge mode in this structure can make the system highly robust to external disturbances. This system provides new ideas for improving the efficiency and security of WPT.
