Optical phenomena in mesoscale dielectric three- and two- dimensional structures

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
