Abstract

The results of numerical modeling of the near field of light wave scattering (“photonic (nano)jet”—PNJ region) by radially symmetric nonabsorbing dielectric microparticles are presented. It is shown that the homogeneous silica microparticles of different spatial shape and orientation form PNJ of different sizes and amplitudes. Photonic nanojets from hemispheres are of high extent but moderate intensity. Use of microaxicons provides for a record increase in the PNJ length of the order of twenty wavelengths of the incident radiation.
