Caption

a, The spectra and schematics of the high-efficiency optical non-Hermitian meta-system at EP. The |r₋₁| is larger than 0.999 and |r₊₁| is less than 10⁻⁴. b, Trajectories of eigenvalues with the evolution of absorption parameter. c, The amplitude of non-specular reflection coefficients r₋₁ and r₊₁ by varying absorption parameter.
