Abstract:
Over a hundred years the magnetic noise has been known in magnetic systems , but the possibility of observing magnetic noise in the optical range in non-magnetic systems has not been reported so far. As shown by simulation, the time-dependent Fano resonance associated with internal Mie modes can be observed at a certain stage of freezing from the outside to the inside of a spherical water drop. In natural precipitation, there is an ensemble of water droplets with different geometric sizes randomly distributed in space. Therefore, such particles (when irradiated by laser radiation) will randomly generate strong electromagnetic fields during freezing, depending on the size of the droplet and the time of its freezing. Such a cloud of freezing droplets can be considered as a natural generator of magnetic noise.
Keywords:Fano resonance, magnetic noise, mesotronics, freezing water drop.
