Finite element method is employed with boundary conditions to analyze the optical properties of the suggested PCFs. HRS and Epsilon Near Zero materials are employed in core and TOPAS as the background material. A wide frequency ranges for 0.8 THz to 2 THz is applied with numerical analysis. Novelty of the paper, we have proposed two Kagome PCFs with different core formations. One PCF is elliptical and rectangular hole based slotted core Kagome PCF, and another one is a circular hole in hexagonal formation based core Kagome PCF. We have investigated the optical properties by tuning the geometry of the PCFs. The main advantages of the proposed PCF are that it shows better results in terms of Dispersion, Birefringence, confinement loss, bending loss, effective material loss, total loss and V-parameters. The results have also been compared with previous papers. Furthermore, the structural design has been described, and numerical results have also been described in this paper. The structure is not complex and can be fabricated by employing well-known fabrication techniques.

Research paper thumbnail of Caching scheme for information‐centric networks with balanced content distribution

This novel networking paradigm makes content retrieval faster and less expensive by shifting data provisioning into content holder rather than content owner. Caching is the feature of ICN that makes content serving possible from any intermediate device. An efficient caching is one of the primary requirements for effective deployment of ICN. In this paper, a caching approach with balanced content distribution among network devices is proposed. The selection of contents to be cached is determined through universal and computed using Zipf's law. The dynamic change in popularity of contents is also considered to take make caching decisions. For balancing the cached content across the network, every router keeps track of its neighbor's cache status. Three parameters, the proportionate distance of the router from the client (pd), the router congestion (rc), and the cache status (cs), are contemplated to select a router for caching contents. The new caching approach is evaluated in the simulated environment using ndnSIM‐2.0. Three state‐of‐the‐art approaches, Leave Copy Everywhere (LCE), centrality measures‐based algorithm (CMBA), and a probability‐based caching (probCache), are considered for comparison. The proposed method of caching shows the better performance compared to the other three protocols used in the comparison.

Research paper thumbnail of Tunable squared patch-based graphene metasurface infrared polarizer

We have identified the resonance response of the proposed polarizer by changing the physical dimensions of the proposed polarizer. The proposed polarizer structure has been investigated for the 1–20 THz of the frequency range. The different physical parameters such as phase variation, polarization conversion rate, reflectance, and transmittance have been investigated for the proposed polarizer structure. Graphene-based polarizer structures are formed with the squared patched geometry, and its complementary condition has been investigated to identify the polarization effect’s behavior. The proposed polarizer device is tunable by various values of graphene chemical potential. The calculated polarization conversion rate (PCR) is > 0.9 for the resonating point, showing the linear to circular polarization conversion. The proposed structure works as a tunable polarizer device where the graphene sheet properties can be controlled from external sources. A resonating band of the polarization effect has been identified from the numerical results of polarization conversion rate and cross-polarization behavior. The phase variation is observed between − 180° and 180° in the graphene patch-based polarizer structure. In contrast, the polarizer structure’s complementary geometry generates the phase variation between 100° and 180°. The proposed polarizer can be easily fabricated using conventional methods as it does not require a complex structure to engrave the graphene sheet. Ultrathin design and tunable properties of the polarizer structure can be used in many photonics and optoelectronics applications.

Applied Physics B, 2022

The proposed structure is investigated numerically from 1 to 7 THz range of frequency. For the different Fermi energy values of the graphene sheet, the graphene-based polarizer is tunable. The Fermi energy of the graphene is ultimately controlled by the external biasing voltages. We present the different results, such as reflectance, transmittance, phase variation, and polarization conversion rate, to identify the behavior of polarizers from the 1 to 7 THz range of frequency. It is achieved the negative effective refractive index at the resonating band which makes the overall structure a metamaterial device. The proposed polarizer shows the wide-angle stability up to 40° of the incident angle. The effect of the different physical parameters was also investigated in this article to identify the suitable resonance frequency. This polarizer structure generates a high-polarization conversion rate which can make this structure work as a linear to the circular polarizer. This structure can work as a basic building block for a large photonics system.

The first, is an operation of encryption, which aims to modify the compressed information to make them unreadable to whoever does not have the necessary authorization to see them. The second is an operation of compression which consists in reducing the size of information to be transmitted, by removing redundant information of them. However, these two operations are often carried out separately, although they are strongly bound and one influences on the other. We propose, in this article, to carry out these two operations (compression and encryption) together in different transform domains. The discrete cosine transform (DCT), the integer wavelet transform (IWT) and the discrete wavelet transform (DWT) are exploited in the proposed encryption approach. Chaotic encryption and lossy JPEG compression are performed in these transform domains to make use of the characteristics of each domain. A comparison study bet...

Chaotic algorithms will be used because they have advantages of its casual Conduct and sensitivity to values of parameters and primary conditions that enable chaotic algorithms to fulfill the cryptographic systems. We consider doing simulation tests using MATLAB codes for logistic 2D map, Henon map, Standard map and baker map. Real simulation results show that baker map with TD exhibits best quality for both encryption and decryption and has a well balance between its advantages and disadvantages among other algorithms in comparison.

The two proposed optical double CM-based FrT image encryption systems are BM-FrT based optical double image encryption and ACM-FrT based optical double image encryption. In the two proposed optical double CM-based FrT image encryption systems, the image is firstly scrambled using the BM or the ACM then, modulated with the first random phase mask, and optically transformed using the FrT. The FrT scrambled image is then again scrambled using the BM or the ACM then, modulated with the second random phase mask and optically transformed with the FrT to get the encrypted image. The usage of a chaotic map as a pre-processing scrambling stage along with the FrT gives the two proposed optical encryption systems the advantages of both the noise immunity from the chaotic map and the security encryption from the FrT. Also, the optical FrT geometric parameters are utilized as additional extra keys that improve the security of the two proposed optical double CM-based FrT image encryption systems. The two proposed optical double CM-based FrT image encryption systems are extensively tested and compared with other encryption systems. The outcomes demonstrated that the proposed BM-FrT based optical double image encryption and ACM-FrT based optical double image encryption enhance the entropy over BM and ACM by a range from 2.02 to 128.23% and 2.06 to 128.16%. The results show that the two proposed optical double CM-based FrT image encryption systems are time-efficient and provide a high level of information security without affecting its noise immunity.
