Abstract
The electromagnetic radiation of nanoemitters placed into a multilayered microsphere with dispersive left-handed (LH) layers included is studied numerically. It is found that in the frequency range where LH layers have a negative refraction index the field frequency spectrum consists of a series of narrow and well separated resonances. In the band of such peaks, the great part of the field energy is located in a LH layer and practically does not leave the microsphere.

Summary
The recently emerging fields of metamaterials and transformation optics promise a family of exciting applications in nanophotonics with the potential for much faster information processing. In very recent experiments [8] it has been demonstrated that the incorporation of gain material in the metamaterial makes it possible to fabricate an extremely low-loss and an active optical NIM that is not limited by the inherent loss in its metal constituent. Since in such materials the electric field, the magnetic field, and the wave vector of a plane wave form a lefthanded system, they are called left-handed materials (LHMs).
