Topological insulators (TI) are new quantum states of matter with insulating bulk states and gapless edge states which is protected by time reversal invariant symmetry. The distinguished electromagnetic response of TI is the Topological Magnetoelectric (TME) Effect.
Here, we explore the fundamental EM scattering problem of TI which may provide a new optical way to detect the TME effect.
Calculating Method: Lorentz-Mie theory TI
