Thin beams with high spatial resolution are widely used in different measurement systems. This paper is devoted to a brief overview of the new and alternative to known approaches to the development of mesoscale systems for localization and transport of electromagnetic fields to the subwavelength region. Our approach is based on mesoscale dielectric particles of arbitrary three-dimensional shape. Its...
The bulk of theoretical studies are devoted to the light jets originated from microparticles with high degree of spatial symmetry like spheres, spheroids, cylinders, disks because of their unique capability to produce extreme spatial field localization. In the current paper we brief review the modern state-of-the art of main principles of the photonic jet formation by non-spherical and non-symmetrical...
