A method which uses the partial element equivalent circuit (PEEC) method an
d electrical network theory to solve for the effective impedance matrix of
reference planes will be presented. The convergence and accuracy of the met
hod are checked. The frequency responses of the effective inductance (L-eff
(f)) and resistance (R-eff(f)) of reference plane will be discussed. The ef
fects of current redistribution and skin effect on L-eff(f) and R-eff(f) wi
ll be discussed. The effect of number of sinks and sources will be examined
.
