  • Abstract
    The authors show that the global matrix in the finite element integro-differential formulation of two-dimensional skin effect problems can be partitioned into the sum of a sparse matrix and a product of two equal arrays for each conductor of the multiconductor system. This partition allows both a great memory saving and a drastic reduction in the conjugate gradient solution time.
