PublicationAntenna design using uwb configuration for gpr scanning applications(Springer Nature, 2019-11)Ultra-wideband (UWB) technology is gaining more attention, as the wireless communication research is progressing with every passing day. This radio technology offers a greater bandwidth with nominal characteristics such as low power, system compactness, and cost-effectiveness. In 1887, first experiment was conducted on UWB for electromagnetic wave production [1]. However, the technology was restricted to military applications only. Thereafter, with the increasing demand of UWB spectrum, US states department Federal Communication Commission (FCC) localized the bandwidth of 7.5 GHz from 3.1–10.6 GHz for the commercial and experimental purpose. Since then, this UWB technology was also used in the development of antenna design, because antennas are the front-end components of the radio frequency (RF) system used in many applications. Therefore, the recent development of RF system is focusing mainly on the search and rescue applications for victim detection behind the obstacle, to make UWB a significant technology. The aim of writing this research article is to highlight the characteristic configuration of a tilted arc-shaped compact size planar antenna design with the frequency ranging from 2.8–15.6 GHz and a gain of around 6 dB for human detection applications. To fulfill the purpose, an antenna is carried out under different configurations for the development of a 2D image in the form of radar cross section (RCS). Thereafter, the analysis is performed to validate the human skin detection capability of the designed antennae. Therefore, a suitable antenna configuration possess proper results is proposed with the help of experimental modeling to proceed further.

PublicationElectrical properties of Sn doped SrTiO₃(AIP Publishing, 2020-01)The crystal structure and electrical properties of SrTiO₃ with addition of 50 mol% SnO2 was studied. Samples were prepared using conventional solid-state reaction route. The results indicate that Sn doped SrTiO₃ was single phase with cubic phase and space group Pm-3m after final sintering temparture at 1400°C. Two semicircular arcs clearly observed in Z" versus Z' plots for SrTi0.5Sn0.5O3 semicircles associated with bulk relaxation processes and grain boundary effect. The heterogeneity of sample was observed form Z' and M" spectroscopic plot. The highest dielectric constant is observed at much higher temperature which nearly 2000 at low frequency measurement.

PublicationComparison between machine learning classifier based on face recognition(IEEE, 2023)With face recognition, machine learning is one of the computer sciences fields that is getting bigger the quickest. The goal of this study is to give a basic overview of machine learning and the algorithmic paradigms it provides. The study gives a detailed explanation of the basic ideas behind machine learning and the math that turns these ideas into methodologies that can be used in the real world, and discusses and compares the performance of various face recognition methods. Machine learning, a field of AI, has emerged as an important part of the digitizing approaches that have attracted a lot of interest. The purpose of this work is to provide a high-level overview of several of the most widely utilized and commonly used algorithmic techniques for machine learning currently available. The goal of this work is to help readers make educated decisions about the best algorithm for machine learning they should employ for a given task by highlighting the benefits and drawbacks of each method from an implementation point of view.

PublicationSecurity of B92 protocol with uninformative states in asymptotic limit with composable security(AIP Publishing, 2020)The security of the Quantum Key Distribution (QKD) is coming from the fundamental principle of quantum physic where any action on the quantum system that tries to extract the information will be considered generally as a measurement which basically will modify the system. The protocol of B92 has been proven unconditionally secure by various of study based on the entanglement distillation protocol (EDP) technique. However, based on this technique it does not prove composable security which is actually important in privacy amplification in order to guarantee the partial key shared cannot revoke the security of the system. We review the security analysis of this system and its implementation in this work.

PublicationSynthesis and physico-chemical characterization of nonlinear optical single crystals of S-carboxymethyl L-cysteine for optoelectronic devices applications(AIP Publishing, 2020)The S-carboxymethyl L-cysteine (SCLC) single crystals have been grown through slow evaporation technique. The lattice parameters of SCLC crystal have been determined using Single-crystal X-ray diffraction. From the transmission spectrum, the optical properties of the SCLC crystals have been investigated. The various functional groups of the SCLC crystal have been confirmed using the Fourier-transform infrared spectroscopy (FTIR). The mechanical properties have been studied using Vickers hardness tester. The nonlinear property is identified by Kurtz and Perry. Further, the electrical properties are studied.
