  • Graphene‑based tunable multi‑band metamaterial polarization‑insensitive absorber for terahertz applications 
    Jain, P.; Bansal, S.; Prakash, K.; Sardana, N.; Gupta, N.; Kumar, S.; Singh, A.K. (2020-12-17)
    This paper presents a graphene-based tunable polarization-insensitive metamaterial absorber (MMA) at terahertz (THz) frequencies. The absorber consists of top patterned gold (Au) layer followed by single layer of graphene, ...
  • Skellam type processes of order k and beyond 
    Gupta, N.; Kumar, A.; Leonenko, N. (2021-06-08)
    In this article, we introduce the Skellam process of order k and its running average. We also discuss the time-changed Skellam process of order k. In particular, we discuss the space-fractional Skellam process and tempered ...
  • Tempered fractional poisson processes and fractional equations with Z-Transform 
    Gupta, N.; Kumar, A.; Leonenko, N. (2021-07-06)
    In this article, we derive the state probabilities of different type of space- and time-fractional Poisson processes using z-transform. We work on tempered versions of time-fractional Poisson process and space-fractional ...
  • Threshold implementations of GIFT: A Trade-Off analysis 
    Jati, A.; Gupta, N.; Chattopadhyay, A.; Sanadhya, S. K.; Chang, D. (2021-07-01)
    Threshold Implementation (TI) is one of the most widely used countermeasure for side channel attacks. Over the years several TI techniques have been proposed for randomizing cipher execution using different variations ...
  • Triple band polarisation sensitive metamaterial absorber for terahertz applications 
    Jain, P.; Singh, A. K.; Bansal, S.; Prakash, K.; Hadda, L.; Gupta, N.; Singh, A. K.; Kumar, S.; Sardana, N. (2021-06-16)
    —In this work, we propose a novel-shaped metamaterial absorber (MMA) for terahertz (THz) applications. The proposed MMA comprises of metallic layers separated by gallium arsenide (GaAs) substrate demonstrating three ...
  • Ultra-thin metamaterial perfect absorbers for single-/dual-/multi-band microwave applications 
    Jain, P.; Singh, A. K.; Pandey, J. K.; Garg, S.; Bansal, S.; Agarwal, M.; Kumar, S.; Sardana, N.; Gupta, N.; Singh, A. K. (2021-07-12)
    In this study, the authors present three different metamaterial absorbers (MMAs) namely, T, split-I (SI) and splitJerusalem cross (SJC) with different dimensions and geometrical configurations. The absorption rates of T-, ...
