In the past, it has been demonstrated that it is possible to produce terajets with high resolution at its focus using 3D dielectric cuboids under plane-wave illumination. Here, a systematic study of the harmonic and angular response of terajets using cuboids is performed. Mutifrequency focusing is demonstrated at the fundamental frequency and two higher(More)
As known, adventure and experience about lesson, entertainment, and knowledge can be gained by only reading a book. Even it is not directly done, you can know more about this life, about the world. We offer you this proper and easy way to gain those all. We offer many book collections from fictions to science at all. One of them is this basic principles of(More)
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(More)
A photonic jet (a terajet at terahertz frequencies) commonly denotes a specific, spatially localized region in the near field on the front side of a dielectric particle with a diameter comparable with the wavelength illuminated by a plane wave on its back side (i.e., the jet emerges from the shadow surface of a dielectric particle). In this Letter, the(More)
In this Letter, we demonstrate applicability of Babinet's principle of complementary diffractive structures for the formation of near-field photonic jets in the reflection mode. Structures, complementary to dielectric cuboids, are characterized with additional geometric and electromagnetic parameters compared to initial cuboids and, for this reason, offer(More)
The task of development of compact light-focusing tools for biomedical applications is challenging due to subwavelength focusing in such devices. In this study we have shown that it is possible to focusing light beyond the diffraction limit by 3D mesoscale particles in application to laser scalpel tips for potential use in ultraprecise laser surgery. The(More)
This paper outlines some of the recent advances in Fresnel zone plate antenna technology. Sidelobe reduction and control over sidelobe location are two developments which are useful for interference reduction. Another development is the focusing resolution of Fresnel zone plate antennas for sub­wavelength focal distances. Designs (More)
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(More)
In this letter we suggest a new approach to the physical principles for hypercumulative plasma jet formation. This new approach leads to several new results which are of fundamental importance. The simulation results of hypercumulative plasma jet are discussed. It has been shown that the increase of the plasma jet speed in the suggested configuration is(More)
