摘要：
Boundary integral equations (BIE) are widely used in applied electromagnetics, with the boundary element method (BEM) typically employed for numerical solution. The paper extends the recently proposed boundary difference method (BDM)-an alternative to BEM-to electromagnetic scattering problems with perfect conductors and with corners. BDM shares several key features and advantages of BEM but avoids the singular kernels inherent in BIE. Convergence rates of the method established via numerical experiments are in agreement with the theoretical predictions.
