Abstract In this paper, the boundary element method (BEM) and the finite element method (FEM) are compared. Then the formulation of Helmholtz equation by BEM and the ealeulation of the reflection coefficient for step-open parallel plate waveguide by BEM are presented. Finally the flow-chart of the program and the computed results are given. Comparison of the computed results for the standing wave state with those given by the related literature shows that the computed results are reasonable.
