Abstract

During the last decade, new unusual physical phenomena in studies on the optics of dielectric mesoscale particles of arbitrary three dimensional shape and gratings with Mie size parameter q ~ 10 have been discovered. The report provides a brief overview of these phenomena from optics to terahertz, plasmonic and acoustic . We also discuss different particle configurations (isolated or interacting, Janus) and draw a brief overview of the possible applications of such mesoscale structures, in connection with field enhancement, nanoparticles manipulation and super resolution imaging. The presence of a number of interesting applications indicates that a new promising direction has emerged in optics, terahertz, plasmonics and acoustics
