Generation of Giant Magnetic Fields in a Hollow Mesoscale Sphere

The superresonance effect for a hollow dielectric sphere is numerically simulated with the Mie theory. It shown first time that weakly dissipative mesoscale spheres an air-filled cavity exhibit high-order Fano resonance related to internal modes. Superresonance in achieved by accurate choice of radius, while monolithic sphere, it ensured outer diameter particle under study. In this case, relative intensities peaks optical range both magnetic and electric fields near poles can have enormous values 10 6 −10 7 , if field magnitude exceeds factor larger than 15 size parameter about 40.
