    Terahertz Light-Field Imaging With Silicon Technologies by U. R. Pfeiffer, A. Kutaish

    Published 2024-01-01
    “…The terahertz (THz) frequency range is widely considered the most challenging and underdeveloped frequency range due to the lack of technologies to effectively bridge the transition region between microwaves (below 100 GHz) and optics (above 10 000 GHz). Although THz radiation would be perfect for material identification and as a safe alternative to X-rays for producing high-resolution images of the interior of opaque objects, first a fundamentally new approach is needed to establish novel devices and techniques.…”

    Analysis of Fractional Kundu-Eckhaus and Massive Thirring Equations Using a Hybridization Scheme by Muhammad Nadeem, Hanan A. Wahash

    Published 2023-01-01
    “…This paper deals with the study of fractional Kundu-Eckhaus equation (FKEE) and fractional massive Thirring problem (FMTP) that appear in the quantum field theory, weakly nonlinear dispersive water waves, and nonlinear optics. Since the variational iteration method involves integration, the Laplace transform involves convolution theorem in recurrence relation to derive the series solution. …”
