Abstract :
In this article, the MoM is replaced by the generalized multipole technique (GMT), and a transition zone between the GMT-zone and PO-zone is employed for iterative improvement of the current continuity. After verifying the effectiveness and accuracy of the GMT/PO hybrid method by means of calculating the numerical diffraction coefficients (NDC) from the classical wedge, several irregular wedges are analyzed using the same methods. A simplification of the iteration procedure is summarized for calculating the NDC in the reflectionless light-region of illumination.
