A permeability-near-zero material has special properties. It is shown that when a source is surrounded by a dielectric split ring with a gap opened, both of which are positioned inside a permeability-near-zero shell, the electromagnetic energy generated by the source is forced to propagate through the gap. When the gap is narrow, the energy stream density becomes very large and makes the magnetic field enhanced drastically in the gap. It is also shown that the radiation of a line current can be greatly enhanced by choosing appropriately the dimension of a dielectric domain in which the source lies and that of the permeability-near-zero shell.
