Abstract [en]

Some of our works on some permeability-near-zero structures will be reviewed. It is shown that when a source is surrounded by a dielectric split ring with a gap opened 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 (inside which the source is located) and the dimension of the permeability-near-zero shell.
