Capturing skin effect with an effective nonuniform mesh and coupled R-L circuits

The frequency dependent inductances and resistances due to skin effect result in inaccurate solutions for electrical interconnect and package design and electromagnetic compatibility modelling. A novel nonuniform mesh approach for rectangular conductors and the calculation of resultant skin effect equivalent circuit elements are proposed. With this procedure, skin effect is effectively characterised by a parallel coupled R-L circuit network with a few elements.
