We first show the existence of a novel non-Hermitian symmetry, i.e., complex mirror symmetry. We then demonstrate a recursive process that generates high-order non-Hermitian degeneracies based on this new symmetry, which can potentially increase the spontaneous emission rate and sensing sensitivity of optical devices by orders of magnitude.
