Generalized P T Symmetry in Non-Hermitian Wireless Power Transfer Systems

We show that, by using a saturable gain gsat, generalized PT (GPT) symmetry can be achieved in the intrinsically unbalanced (non-PT-symmetric) high-order wireless power transfer systems. A topology decomposition approach is implemented to analyze the parity of the high-order wireless power transfer systems. In the coupling parametric space, a global GPT-symmetric eigenstate is observed along with the spontaneous phase transition of the local GPT-symmetric eigenstates on the exceptional contour. GPT symmetry guarantees a highly efficient and stable power transfer across the distinct coupling regions, which introduces a new paradigm for a broad range of application scenarios involving asymmetric coupling.
