Topological properties of one-dimensional non-Hermite electromagnetic medium system

In this paper, we establish a one-dimensional periodic dielectric systems based on one-dimensional maxwell's equations, with abundant topological phase. Through the analysis of the system of chiral symmetry, the energy spectrum of the system and topological phase diagram under the influence of various parameters, particularly is a Hermitian topological phase diagram. By further numerical calculation of the energy spectrum and eigenfunction system, found a 0 or a PI energy advantage state borders, and around the edge with the number of boundary value is consistent, indicates that the system meet the volume boundary correspondence principle.
