    Dual band operation using metamaterial structure for Radio Frequency Identification (RFID) system
    (IEEE Computer Society help@computer.org, 2014) Saha, R.; Bhattacharjee, S.; Bhunia, C.T.; Maity, S.
    The important functions of Radio Frequency Identification (RFID) technology are radiation and detection. So efficient antenna design and fabrication is the unique solution which perform a very crucial role for many applications. The reader and tag intense are component of the RFID system. In this paper designed has done on RFID antenna for tag and reader application, which also includes the different types of antenna (UHF application, wideband, multiband antenna) and the general consideration for design, them which are currently used for tag and reader application. In this paper we proposed a rectangular patch antenna and then designed a metamaterial structure on the patch to improve the antenna performance. © 2014 IEEE.

    Reduction of reflectance at c-silicon solar cell using nanotexturization
    (Institute of Electrical and Electronics Engineers Inc., 2014) Maity, S.; Kundu, A.; Das, S.; Chakraborty, P.
    Reduction in reflection losses of bare silicon surfaces has always attracted many researchers as it by far remains the most important criterion needed for achieving high efficiency solar cells. Anti-reflection coatings (ARC) of dielectrics help in balancing the refractive index mismatch between silicon and air. Although such ARCs help in reducing the reflection losses, they do not cause bending of light rays which is essential for efficient light trapping of the injected light into the cell. The technological leaps in the last few decades have lead to the possibility of nanotextured surfaces comprising of sub-wavelength structures in the optical domain. We report a simple and fast process for nanotexturing of the silicon surface may be achieved by creating silver nano-islands on the silicon surface and etching the exposed silicon surface. © 2014 IEEE.

    A Novel Approach of Network Security Using Genetic Algorithm
    (Springer Science and Business Media Deutschland GmbH, 2024) Bera, A.; Sinha, D.; Maity, S.; Paul, S.
    This article focuses on providing security of sensitive information and message transmission using symmetric key cryptosystem based on genetic algorithm and combined with mathematical and bitwise operators to provide confidentiality, authenticity, integrity, and nonrepudiation of the messages. A plain text is encrypted using a private key and resizer parameter taken as input from the user to produce an intermediate cipher which is further encrypted using genetic algorithm and mathematical operations to obtain the final cipher. The level of complexity of encryption and the size of the final cipher text can be regulated using the resizer parameter. The final cipher is decrypted first to obtain an intermediate cipher, which in turn is decrypted using the private key to get back the plain text. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
