  Broadband light illumination of a mesoscale dielectric sphere makes it
possible to reveal new effects that associated with super resonance mode. These
include the possibility of generating high-order Fano resonance cascades. The
quality factor has the order Q=10^7. Super-resonance-enabled subdiffraction
fields localization by mesoscale dielectric sphere under broadband light
illuminations (e.g., at wavebands of 400 - 700 nm for refractive index of
sphere n=1.5-1.9 and 1500 - 1600 nm for n=3.47) have been investigated. The
conditions for the quasi-periodicity of superresonance peaks are established.
The dependence of the amplitude modulation of Fano cascades on the refractive
index of the sphere is shown. These results are important in deep understanding
of physics of the super-resolution mechanism related to superresonance mode and
will find great potential applications in many other area.
