Аннотация

By the numerical simulation we predict acoustic super-resonance modes with several tens of thousands of times field-intensity enhancement (order of magnitude: 10 4 - 10 5 ) supported by dielectric mesoscale spheres immersed in water. The super-resonances are related to internal scattering at specific values of the Mie and the particle material parameters and they are responsible for generation of giant fields within the particles near its surface. Taking into account the analogy between electromagnetic and acoustic waves this phenomenon is valid in electromagnetic (optical) waveband.
