A spatial superposition approach is employed to compute the fringe currents. The locally conformal perfectly matched layer approach is used to truncate the infinitely long conducting structure in a finite sized domain. MATLAB codes are developed, and some numerical examples are demonstrated. The results are compared to those of the physical theory of diffraction and the method of moments.eninfo:eu-repo/semantics/closedAccessDiffractionfinite element method (FEM)fringe currentsfringe waveshigh-frequency asymptoticslocally conformal perfectly matched layer (PML)physical theory of diffraction (PTD)wedgeArticleQ2Q116369372WOS:000399311000092
