Abstract
The topological magnetoelectric effect (TME) is a unique macroscopic manifestation of quantum states of matter possessing topological order and it is described by axion electrodynamics. In three-dimensional topological insulators, for instance, the axion coupling is of the order of the fine structure constant, and hence a perturbative analysis of the field equations is plenty justified. In this paper we use Green's function techniques to obtain time-dependent solutions to the axion field equations in the presence of a planar domain-wall separating two media with different topological order. We apply our results to investigate the radiation of a short linear antenna near the domain-wall.
