Özet
The finite element method is applied to the modeling of fringe currents and fields in a diffraction problem, where a perfectly conducting wedge is illuminated by a line source. 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.
