Realization of complex conjugate media using non-PT-symmetric photonic crystals
Xiaohan Cui, Kun Ding, Jianwen Dong +1
While parity-time (PT)-symmetric systems can exhibit real spectra in the exact PT-symmetry regime, the PT-symmetry is actually not a necessary condition for the real spectra. Here…

Exceptional points and their coalescence of PT-symmetric interface states in photonic crystals
Xiaohan Cui, Kun Ding, Jian-Wen Dong +1
The existence of surface electromagnetic waves in the dielectric-metal interface is due to the sign change of real parts of permittivity across the interface. In this work, we demo…
