Exploring Generalized PT-Symmetry for Efficient Wireless Power Transfer
A wireless power transfer (WPT) system of dynamically high and stable power transfer efficiency is proposed based on generalized parity-time (GPT) symmetry. By introducing a saturable gain, gsat, GPT-symmetry can be reconstructed in non-Hermitian systems dominated by intrinsically unbalanced coupling. The parity of the system can be analyzed by a topology decomposition approach. In the coupling parametric space, a global GPT-symmetric eigenstate is observed, and the spontaneous phase transition of the local GPT-symmetric eigenstates is identified on the exceptional contour. A band theory interpretation is proposed to analyze the efficiency-compromised states. Our study shows that the global GPT symmetric state corresponds to an efficient and stable power transfer across the distinct coupling regions, which provides insight into practical WPT systems involving asymmetric coupling.
