Abstract. The electromagnetic radiation of nanoemitters placed into a microsphere with metamaterial (dispersive left-handed -LH) layers was studied numerically. Such an investigation cannot be done analytically; it requires intensive numerical simulations with the use of the Green tensor technique and specific algorithms for the spherical functions. All of that leads to intensive consuming of the computer resources. As a result of computer experiments 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. Such conclusions were obtained as a result not only simulations, but also of a human computer interaction. We discuss the aspects of the advanced Human Computer Interaction with GUI and Usability that were developed in our study and that has allowed us to explore deeply such a complex nanosystem. |
