The results of numerical modeling of the light wave scattering near field (“photonic (nano)jet” – PNJ area) by radially symmetric nonabsorbing dielectric micron-sized particles are presented. It is shown that the homogeneous silica microparticles of different spatial shape and orientation form PNJ with different dimensions and amplitude parameters. Photonic nanojet from hemispheres possesses high extent but moderate intensity. Using of microaxicons provides for a record increase in the PNJ length of the order of twenty laser wavelength.
