Paper Abstract

The near field of scattering of an optical wave (zone of photonic jet (PhJ)) at radially symmetric nonabsorbing micronsized dielectric particles is numerically simulated with an emphasis at the study of size and amplitude parameters of photonic jets from quartz microparticles of various spatial shape and orientation. Photonic jets from hemispheres are shown to have the long length, but relatively low intensity. The use of conical particles of a certain shape gives a record increase of the PhJ length up to two tens of wavelengths of the incident radiation (at the fixed intensity level) at the preserved subwavelength transverse dimension of the photonic jet.
