Circuit Simulation of Any Time-Domain Source on Fractional-Order Impedances by Use of the Haar Wavelet Transform, Case Study of the Skin Effect

Year: 2025

Type: article

Abstract: An application of the ability of the Haar wavelet operational matrix to perform the numerical inverse Laplace transform as combined with the intrinsically convenient Haar wavelet transform of any time-domain signal is presented in this paper. A case study of the transient-and steady-state behavior of the input impedance of a short-circuited transmission line showcases a method to perform the numerical inverse Laplace transform of fractional-order approximative expressions of the skin effect. Furthermore, an improved skin effect approximation is presented.
