A METHOD FOR ASSESSING THE INFLUENCE OF GEOMETRIC IMAGE DISTORTIONS ON THE RESULTS OF THEIR COMPARISON WITHIN THE CORRELATION-EXTREME ALGORITHM , V. BYKOV, K. KOZIS, , V. KHARDIKOV, , Y. KOZHUSHKO, , T. BEREZHNA, and Space Science and Technology, 2025 The article presents a comprehensive study of methods for quantifying the potential accuracy of determining the coordinates of various types of objects using matrix correlation-extreme navigation systems. Three main categories of objects are considered: point objects (occupying a small part of the frame), extended objects, and planar objects (occupying a significant part of the frame), which can be either tangent or non-tangent to the observation system. Particular attention is paid to the analysis of factors that affect the accuracy of measuring the coordinates of these objects. These include geometrical parameters of objects, their spatial orientation, contrast rela- tive to the background, lighting conditions, atmospheric phenomena, and technical characteristics of matrix sensors. Mathematical models describing the relationship between these factors and the potential measurement accuracy are presented. The peculiarities of step-by-step object navigation using matrix correlation-extreme navigation systems are investigated, which can significantly improve the accuracy of coordinate determination. The algorithms for optimising the process of sighting, accounting for the specifics of different types of objects, are proposed. The methods of compensation for systematic errors and minimisation of the influence of random interfer- ence are considered. The results of experimental studies confirming the effectiveness of the proposed methods of accuracy assessment are presented. It is established that with the optimal choice of system parameters and information processing algorithms, it is possible to achieve high accuracy in determining the coordinates of all types of objects under study. The developed methods and algorithms can be effectively used in the design and configuration of matrix correlation-extreme navigation systems for various practical applications, including navigation systems for robotic systems and other moving objects, where high accuracy of coordinate determination relative to ground reference points is required. The obtained results create a theoretical basis for further improvement of methods for increasing the accuracy of matrix correlation-extreme navigation systems and expanding the scope of their practical application.
DEVELOPMENT OF A METHOD FOR SIMULATING THE PROCESS OF IMAGE COMBINATION IN CORRELATION-EXTREME NAVIGATION SYSTEMS , V. BYKOV, G. OSINOVYY, , K. KOZIS, , V. KHARDIKOV, , Y. KOZHUSHKO, , T. BEREZHNA, and Space Science and Technology, 2025 The purpose of the article is to obtain an average estimate of the accuracy of determining the coordinates of an aircraft using the method of simulating the process of combining the current image with the reference image in correlation-extreme navigation systems. For this purpose, the article considers a correlation algorithm for solving the problem of combining the current image with the reference image and examines how the key distortions that arise during the current image formation impact this algorithm. The difference in the scales of the current image and reference image, the rotation of these images relative to each other, and the presence of random noise are considered distortions. Correlation-extreme navigation systems are a promising area in the field of platform-free inertial navigation systems. The principle of their operation is based on comparing the current terrain image obtained from the onboard optoelectronic system with a reference image previously stored in the system’s memory. Determining the offset between these images allows you to calculate the coordinates of the navigation object. However, due to a number of factors, such as changes in flight altitude, object tilt, atmospheric effects, etc., the current image may undergo various transformations compared to the reference image. This complicates the process of alignment and reduces the accuracy of navigation calculations. To improve the reliability of the system, it is necessary to take these transformations into account and compensate for their impact. In this paper, we model the process of image fusion, taking into account scale differences, rotatio, and other transformations. Various algorithms of image fusion are considered, such as correlation analysis, contour matching, phase correlation, and others. Their efficiency and robustness to various types of transformations are evaluated. The modeling results allow us to determine the optimal parameters of the algorithms, the ranges of permissible transformations, and the average accuracy of navigation calculations for different operating conditions of the correlation-extreme navigation systems. This information is useful for developers of navigation systems, as it allows them to increase their efficiency and reliability.

Tunable Metasurface Based on Crossed Strip Gratings Consisting of Nonreciprocal Materials Vladimir V. Yachin, Vyacheslav V. Khardikov, Liudmyla A. Kochetova, Sergiy L. Prosvirnin 2024 54th European Microwave Conference Eumc 2024, 2024 A non-reciprocal metasurface formed by two crossed strip gratings, the upper of which consists of a magnetically active material (ferrite), and the lower of a dielectric (silicon), is proposed and studied. The possibility of achieving mechanical tuning of the resonance response of the considered metasurface when rotating the strip gratings relative to each other is shown. The phenomenon of extraordinary enhancement of the Faraday effect when using metasurface resonances of this type has been demonstrated. Two factors that allow reconfiguration in the metasurface under study are: firstly, the mechanical rotation of the strips relative to each other and, secondly, the adjustment of the amplitude of the magnetizing field. Thanks to this, we can change the scattering characteristics of the metasurface over a wide frequency range, which is necessary for designing the non-reciprocal devices.
Experimental observation of diffractive retroreflection from a dielectric metasurface Anton S. Kupriianov, Vyacheslav V. Khardikov, Kateryna Domina, Sergey L. Prosvirnin, Wei Han, Vladimir R. Tuz Journal of Applied Physics, 2023 The non-specular reflection scenario is considered important for many practical applications of gratings because this regime corresponds to the maximum efficiency of diffraction. Retroreflection is a particular case of a non-specular scenario when a grating returns a large portion of the incident light back to its source. We propose a detailed quasi-optic (microwave) experimental study of the retroreflection phenomenon in dielectric metasurfaces. Our study is supplemented by an analytical description and full-wave numerical simulation. The experimental sample of the metasurface is constructed as an array of disk-shaped low-loss ceramic resonators inserted in a host with air-like material properties. To ensure efficient reflection, the metasurface is coated on one side with a metallic foil. The conditions of retroreflection for any direction and polarization of an incident wave are demonstrated in both far-field and near-field experiments. The main contribution to the non-specular reflection of the Mie-type (HE 11) mode of the disk-shaped resonators forming the metasurface is revealed. The high efficiency of retroreflection in both TE (transverse electric) and TM (transverse magnetic) polarizations allows us to consider our metasurface as a prototype of planar grating rulers for high-precision displacement measurements.
Resonant Response in Tunable Metasurface Based on Crossed All-Dielectric Grating Vladimir V. Yachin, Vyacheslav V. Khardikov, Liudmyla A. Kochetova, Sergiy L. Prosvirnin 2023 53rd European Microwave Conference Eumc 2023, 2023 We theoretically demonstrate mechanical tuning of the spectral response of a Mie-like resonant dielectric metasurface consisting of crossed all-dielectric strip gratings. We use two array of parallel dielectric strips superimposed on each other to mechanically alter the crossing angle between them thereby changing the position of the maximum of the spectral response in a wide frequency range. The metasurface structure is considered as a doubly-periodic system in an oblique mesh. This mechanically controllable metasurface can be perspective in developing of a flexible polarization-sensitive optical devices.
INTENSITY CONTROLLED, NONSPECULAR RESONANT BACK REFLECTION OF LIGHT , S. Prosvirnin, , V. Khardikov, , , V. Yachin, , V. Plakhtii, , N. Sydorchuk, and Radio Physics and Radio Astronomy, 2022 Subject and Purpose. Theoretical demonstration of controllable features of a non-conventional resonant back reflection of light, realizable with the aid of a structured silicon-on-metal covering. Methods and Methodology. The investigation has been performed through a full-wave numerical simulation in a finite-element technique. Results. The nonlinear optical properties of a planar structure, involving a set of silicon disks disposed periodically on a silver substrate, have been studied in the Littrow scenario of wave reflection. The structure manifests a bistable resonant reflectivity property. The magnitudes of both specular and back reflection ratios can be controlled by means of varying the incident light intensity. Conclusions. An array of identical silicon disks, placed in a periodic order on a silver substrate, can be employed as an efficiently excitable and tunable nonlinear resonant reflective structure implementing Littrow’s non-specular diffraction scenario. As has been found, the effect of nonlinear response from the silicon disks can be used for implementing a regimen of bistable back reflection, controllable by means of varying the incident wave’s intensity. The nonlinear tunability of the silicon-on-silver structure does promise extensions of the operation area of classical metamaterials of sub-wavelength scale sizes as it offers new
Features of resonant interaction of light with all-dielectric metasurface formed by chiral particles Vyacheslav Khardikov, Vladirim Yachin, Sergiy Prosvirnin Proceedings of International Seminar Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory Diped, 2021 The paper deals with polarization transformation of light transmitted through all-dielectric metasurface with chiral elements. The base chiral particle is formed by two silicon blocks rotated relative to each other at a certain angle. To demonstrate the influence of bulk chirality on polarization state of transmitted light it is considered placing the bars into two different adjacent layers. It will be shown dependence of polarization state of transmitted and reflected light on eigen states of the base element of metasurface.
