On Applications of Elements Modelled by Fractional Derivatives in Circuit Theory

open access: yesEnergies, 2020
In this paper, concepts of fractional-order (FO) derivatives are reviewed and discussed with regard to element models applied in the circuit theory. The properties of FO derivatives required for the circuit-level modeling are formulated.
