Abstract:
Using the quasi-static approximation we have found exact analytical solutions to the problem of the field of a point electromagnetic source in the presence of a layer of a bi-isotropic (chiral) metamaterial. At some parameters of the problem, the resulting solution can be represented as a set of several point sources (electric and magnetic), which are images of the original source. If the original source is located near the layer, these images become real sources of the field. This paradoxical solution is then generalised to the case taking into account the retardation effects, which allows one to physically interpret the obtained solutions as a set of sources and 'sinks' of circularly polarised waves.
Keywords:
