A singularity problem arises in the computation of MoM matrix entries. Several singularity cancellation schemes are proposed in literature. One of these singularity cancellation methods is applied to handle the singularity problem associated with the MoM analysis of 2D periodic structures. For the efficient computation of the 2D periodic Green's function, Ewald transformation is used, resulting in a change in the kernel of the integral associated with the MoM matrix entries. Formulation of the problem for this new kernel is presented together with numerical results for a sample problem.
