Manifestation of chiral edge state in both reciprocal and real space.
(a,b) Perfect analogy of TSC Hamiltonian and edge state with ideal material parameters. (a) Projected band diagram of infinite TSC-like photonic structure (shaded areas) and edge state at the interface between a semi-finite TSC-like medium in the region x > 0 and a semi-finite opaque medium in the region x < 0 (red line). (b) Magnetic field (Hz) distributions of edge state for a finite TSC-like medium. (c,d) Non-perfect TSC-like edge state with reduced material parameters. The results in (a) and (c) are analytically calculated by solving Maxwell's equations and those in (b) and (d) are numerically simulated by employing FDFD method.
