| Popis: | We study the near-field enhancement of oligomers composed of high-refractive-index spherical particles. The huge enhancement of the electromagnetic field in the gap between the particles is observed. We reveal that this phenomenon is associated with the Fano-like resonances of both electric and magnetic multipole contributions inside each particle. We also predict that electric and magnetic Purcell factors can be strongly enhanced, being larger than 10 3 . The obtained results represent an important guideline for the realization of dielectric structures to enhance the spontaneous emission rate of quantum sources and various two-level systems. |
