New effects at resonant light scattering by nanoparticles

A brief survey of the recent accomplishments of the author in the old problem of light scattering by small particles is given. It is shown that in certain cases, the scattering has very little in common with the conventional Rayleigh case. New, counterintuitive effects are pointed out, inspected, discussed, and classified, especially those related to violating the quasi-static description of the scattering occurring at the action of (ultra)short laser pulses. Among them are anomalous scattering; Fano resonances; giant electromagnetic field concentration near the scattering particle and inside it; tunable scattering diagrams; etc. These effects provide a unique opportunity to tailor and control the radiation patterns at the essentially subwavelength scales and open the door to new nanotechnologies as well as to the design and fabrication of a new generation of nanodevices, including multifunctional ones.
