It is shown for the first time that weakly dissipative mesoscale spheres with an air-filled cavity exhibit a high-order Fano resonance related to internal Mie modes. Superresonance in a hollow sphere is achieved by the accurate choice of the cavity radius, while for a monolithic dielectric sphere, it is ensured by the accurate choice of the outer diameter of the particle under study. In this case, the relative intensities of the resonance peaks in the optical range for both magnetic and electric fields near the sphere poles can have enormous values of 10<sup>6</sup>−10<sup>7</sup>, if the magnetic field magnitude exceeds that of the electric field by a factor larger than 15 for the hollow sphere with a Mie size parameter about 40.</p></abstract><trans-abstract xml:lang="ru"><p>На основе теории Ми представлены результаты численного моделирования эффекта суперрезонанса для полой диэлектрической сферы. Впервые показано, что слабодиссипативные мезоразмерные сферы с воздушной полостью поддерживают резонанс Фано высокого порядка, связанного с внутренними модами Ми. Достижение суперрезонанса в полой сфере обеспечивается точным выбором радиуса полости, в то время как для монолитной диэлектрической сферы он обеспечивается точным выбором внешнего диаметра частицы. При этом относительные интенсивности резонансных пиков как для магнитного, таки электрического полей в окрестности полюсов сферы в оптическом диапазоне могут достигать огромных значений порядка 106-107 при превышении интенсивности магнитного поля над электрическим более 15 раз для полой сферы с параметром размера Ми около 40.</p></trans-abstract><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>B.
