“…In [12], the suck-out effect of high-speed transmission lines was explained by using periodic structure, where the full-wave simulation method was used. Moreover, the electromagnetic compatibility (EMC) of shielded twisted/untwisted pair shielded high-speed transmission line cables for automotive multi-Gig Ethernet application was investigated by using the mixed-mode S parameters in [13].…”

An efficient transmission line model of high-speed cables is established, to predict its response at a high-frequency region (up to 20 GHz). Especially, an appropriate conformal mapping technique is applied to formulate the per-unit-length parameters of high-speed cables. Moreover, the skin and proximity effects of the conducting wires and the outer shield are derived in the closed form. As a result, the AC resistance/ inductance of all the conducting materials due to the skin and proximity effects are accurately incorporated for both layered and unlayered conductors. Furthermore, the mixed-mode S-parameters are precisely predicted for both balanced and unbalanced transmission line cables in the high-frequency region. In addition, the effects of the nonuniformities and cable geometry deformation on the mode conversions are also investigated. The proposed model is firstly validated with commercial software tools, COMSOL, FEKO, and HFSS; then, we further performed physical measurements to verify our new algorithm.INDEX TERMS High-speed cable, transmission line model, mixed-mode S-parameters, common-mode (CM), differential-mode (DM), shielding, fixtures, skin effect, proximity effect.
