A new boundary element method (BEM) for analyzing the potential field including thin plates is developed. It is known that the inaccurate solutions are encountered with the standard BEM for this potential problem. In case each source point on foreside and backside of the thin plate is close, the boundary integral equations for these sources nearly depend each other. This is because the fundamental solution distributions for each source are almost the same. In order to overcome this problem, the special weighting function whose form is not symmetric instead of the standard fundamental solution in the BEM is proposed. The weighting function for 2 D potential problem is derived. A few example problems are solved with this method to demonstrate its applicability and usefulness.
