A fast approach is developed here to analyze large finite planar periodic arrays of elements in a grounded multilayered medium with relatively arbitrary element truncation boundaries. An array shape matrix is introduced which contains information on the array element truncation boundary, and it can be easily incorporated into preconditioned iterative method of moments matrix solvers without significantly increasing computational resources. The performance of the present approach is illustrated through numerical results.
