| الملخص: | Title screen We report on the results of numerical simulation based on the Mie theory of the super-resonance effect (the higher-order Fano resonance) for a mesoscale dielectric sphere located in air, since the vacuum environment is an idealization that is almost never encountered in nature. It is first shown using the example of a particle with a refractive index of 1.5 and size parameters of q ∼ 26 and q ∼ 38 that a change in the refractive index of the environment by 2 × 10−4 leads to drop in field intensity in the region of the shadow pole of a sphere by an order of magnitude and a shift in resonance size parameter q to the short-wavelength region. In this case, the relative intensities of the resonance peaks for both the magnetic and electric field in the vicinity of the sphere poles in the optical range can attain these values (106‒107) for a particle in vacuum with an appropriate correction of the resonance size parameter Текстовый файл AM_Agreement |
