abstract = {This article introduces a comprehensive methodology
for analyzing common-mode (CM) ferrite chokes in time-domain
(TD) methods, employing lumped dispersive loads, and validates it
through a typical test setup for cable crosstalk assessment. The
analysis begins with the experimental characterization of CM
choke material properties using a coaxial line fixture to obtain its
constitutive parameters. Subsequently, a simplified lumped dispersive convolutional model is obtained, representing the impedance
of the ferrite when placed on a location on the cable. The first approach adopts a multiconductor transmission line (MTL) model for
the cables, solving them by a finite-difference (FDTD) space-time
scheme. The second approach utilizes the classical full-wave YeeFDTD method in conjunction with the thin-wire Holland model for
cables. The accuracy of the proposed methods is evaluated by comparing simulations performed with MTL-FDTD and Holland-Yee
FDTD, to experimental measurements, and results obtained with
the the frequency-domain finite element method using a 3-D model
of the ferrite with its constitutive parameters. Finally, the validity
and performance of the methodologies are critically discussed.},
