An Iterative Method based on MoM Algorithm with Memory Requirements in the Order of O(N)

A rigorous and modified iterative method of moments (MoM) algorithm is presented, by changing the sequence of the conventional iterative MoM algorithm, the memory requirement has been reduced greatly, which is with order of O(N), while, the operations complexity of matrix-vector multiples for each iteration remains to be at the order of O(NiterN
²
). We utilize generalized minimum residual method (GMRES) as iterative solver here, some examples are analyzed to verify the method.
