An Efficient Finite-Difference-Based Newton-Raphson Method to Determine Intrinsic Complex Permeabilities and Permittivities for Mn-Zn Ferrites

摘要

This paper presents a fast and efficient algorithm, based on the finite-difference method, to extract intrinsic complex permeability and permittivity from measured values for Mn-Zn ferrite cores. Our algorithm is considerably more efficient than the analytical solution-based Newton-Raphson method and reduces computing time from hours to tens of seconds.
