Photonics of mesoscale nonspherical and non axysimmetrical dielectric particles and application to cuboid-chain with air-gaps waveguide based on periodic terajet-induced modes

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 dielectric mesoscale particles (like axicon, triangle bar, cubic, hexahedron, etc) both in transmitting and reflecting modes and some of application to waveguide. A deeper understanding of the photonic jet is nevertheless needed to fully exploit the potential performance of nano- and micro- dielectric mesoscale objects as diffractive components at different wavebands.
