- Аннотация: This paper presents a brief review of resonance scattering of light by subwavelength particles with a large refraction index and small dissipation. It shows that each partial mode can be represented outside the particles as a superposition of infinite cascades of Fano resonances. The nature of these resonances is explained. Simple relationships are given that directly express the parameters of an asymmetric Fano line in terms of the particle size, the wave number of the incident radiation, and the complex refractive index. The resonances are characterized inside the particles by a traditional Lorentzian line shape; however, the amplitude of the resonances can be very large, while resonances of various orders can substantially overlap. This creates conditions for giant (by orders of magnitude) amplification of the field inside such a particle, as well as for controlling the contrast of this field. The indicated properties open up new possibilities for creating nonlinear heterogeneous nanostructures and other metamaterials.
