On the quantification of the state-of-the-art models for skin-effect in conductors, including those with non-rectangular cross-sections

Predictability of transmission line parameters in both the frequency and time-domains is very important for microelectronics packaging. Proximity effects and non-rectangular cross-sections can cause a drastic deviation in transmission line parameters from the theoretically calculated values. Filament models and full-wave techniques have offered improvements over analytical models for computing the parameters of transmission lines with arbitrary cross-sections including proximity effects. This work is an analysis of some state-of-the-art skin-effect models and a quantification of their limitations.
