FIG. 1.

A light amplification system composed of ZIM and the inserted gain medium in polar coordinates. The point source is embedded inside the ZIM but not touches the gain medium.

FIG. 2.

Snapshots of magnetic field distribution for [(a) and (b)] one and [(c) and (d)] two gain inserts located in ZIM. The positions of inserts and point source in (a)–(d) are different.

FIG. 3.

Comparison of magnetic field distributions at for four panels in Fig. 2. The dash-dotted curve (dark yellow) shows the imperfect magnetic field distribution using quasi-ZIM with .

Image of FIG. 4.
FIG. 4.

Variation of amplification ratio with imaginary part of permittivity for the cases of single gain insert (squares), double gain inserts (circles), and single gain insert accompanied with a lossy insert, which has permittivity 2 + 0.2 i (triangles) or 2 + 0.1 i (stars).
