ABSTRACT
The description of memory effects in wave propagation and anomalous diffusion is best analyzed using the time-fractional telegraph equation (TFTE), widely applicable in fluid flow, signal transmission, and biological systems. In this paper, the analytic solution of TFTE in the whole space-domain and in a half-domain is investigated using the Mamadu integral transform. For a reliable and accurate representation of hereditary and nonlocal properties in TFTE, the fractional derivatives are defined in the Caputo sense. The Mamadu Transform converts the problem into an algebraic equation to ease the solution process. The contour integration is then employed to compute the inverse Mamadu Transform, where the solution structure is determined at the poles of the transformed function via the residue theorem. Additionally, the spatial characteristics of the solution are reconstructed through the inverse Fourier transform, ensuring an adequate representation in the transformed domain. Using specific values for the parameters α,β,a,b and c, we analyze the system response by evaluating the resulting characteristic equation. The results depict the effectiveness of the Mamadu Transform, in conjunction with the inverse Fourier transform for solving the TFTE, offering systematic and flexible techniques to handle diverse problems in a complex domain.
