The Superresonance Effect in a Low-Index Mesoscale Sphere

Results of numerical simulation of the superresonance effect in a dielectric (water) mesoscale sphere with a low refractive index based on the Mie theory are presented. They shown that not only the previously studied weakly dissipative mesoscale spheres made of a material with "medium" (similar to 1.5) and high (>2) refractive indices, but also low-index (similar to 1.3) spheres support the high-order Fano resonance effect associated with internal Mie modes. The intensities of resonant peaks for both magnetic and electric fields can attain extremely high values on the order of 10(6)-10(7) in the vicinity of the poles of a water droplet with a Mie size parameter of similar to 70.
