Assuming d ⁱ _II = 2 d and s ⁱ _II = d, from (15.3), the mutual inductance between the power and ground paths of the different voltage domains for a pseudo-interdigitated power distribution grid with DSDG is

Substituting (B.1) (B.4) into (15.8), the mutual inductive coupling M ^intII _loop between the two current loops in a pseudo-interdigitated power distribution grid with DSDG is

Simplifying (B.5) and considering that ln ? and ln k are approximately the same for different distances between the lines, M ^intII _loop is
