Formulation of Time-Fractional Electrodynamics Based on Riemann-Silberstein Vector
Entropy, 2021 In this paper, the formulation of time-fractional (TF) electrodynamics is derived based on the Riemann-Silberstein (RS) vector. With the use of this vector and fractional-order derivatives, one can write TF Maxwell’s equations in a compact form, which ...
