“…Photonics 2021, 8, x FOR PEER REVIEW 3 of 12 min, the solidified PDMS cube was obtained from the hole-type pattern. Some details of the technological process may be found in References [21,37]. A scanning optical microscope system was used to measure the focusing performances of the DMC with and without metal masks.…”

“…The simulations and experimental results are in reasonable agreement. The discrepancies between the simulations and the experiments in Figure2are due to the influence of the substrate in the experiments, which the DMC is placed on[37]. As seen from the figures, the presence of a dielectric substrate imposes oscillating behavior to the field intensity distributions in experiments due to multiple field reflections from the silicone substrate and non-constructive interference[39,40].…”

In this study, we present the simulations and experimental observations of photonic jet (PJ) shaping by control of tangential electric field components at illuminating wavelengths of 405 nm, 532 nm, and 671 nm. The PJs are generated by a single dielectric 4-micrometer cube that was fabricated from polydimethylsiloxane (PDMS). The dielectric cube is deposited on a silicon substrate and placed on two aluminum masks with a width equal to the side length of the cube. Due to the appearance of the metal masks, the focal length and decay length of the generated PJs decreased almost twice, while the PJ resolution increased 1.2 times. Thus, PJ shaping can be controlled by the presence of the metal mask along the lateral surface of the cube without changing the external shape or internal structure of the cube. This effect is based on the control of the tangential components of the electric field along the lateral surface of the cube. In the case of a one-sided metal mask, the effect of optical deflection and bending is predicted to form a photonic hook. Due to the low cost of these dielectric cubes, they have potential in far-field systems to better meet the requirements of modern optical integration circuits and switches.

“…The property control of the spatial propagation of narrow light beams such as divergence and focusing, are the main problems in optics and photonics. Another interesting photonic jet effect is that the dielectric-metal thin rectangular structure can function as a flat focusing mirror [27,28,92]. The new type of a planar device without the pre-specified optical axis [92] provides focusing in the near-field region, where the structured reflected beam demonstrates non-diffracted propagation by a distance of the photonic jet length and can significantly enhance the applicability of the structured photonic systems to control the light beam propagation in mesoscale photonic circuits.…”

During the last decade, new unusual physical phenomena have been discovered in studying the optics of dielectric mesoscale particles of an arbitrary three-dimensional shape with the Mie size parameter near 10 (q~10). The paper provides a brief overview of these phenomena from optics to terahertz, plasmonic and acoustic ranges. The different particle configurations (isolated, regular or Janus) are discussed, and the possible applications of such mesoscale structures are briefly reviewed herein in relation to the field enhancement, nanoparticle manipulation and super-resolution imaging. The number of interesting applications indicates the appearance of a new promising scientific direction in optics, terahertz and acoustic ranges, and plasmonics. This paper presents the authors’ approach to these problems.
