Popis:	We predict acoustic super resonance modes with a field-intensity enhancement several tens of thousands of times higher (order of magnitude: 104 -10 5) with the support of dielectric mesoscale spheres submerged in water, by means of numerical simulations. The super resonances are related to the internal dispersion in specific values of both Mie and particle material parameters, being responsible for the generation of giant fields within the particles and near its surface. Taking into account the analogy between electromagnetic and acoustic waves, this phenomenon is valid in the electromagnetic (optical) wave band.
