Abstract With the concept of virtual boundary in elasticity, the paper combines radial basis function (RBF) method and traditional boundary element method (BEM) to form the RBF-virtual boundary method, and applies it to the numerical computation of electromagnetic field. The method not only has the advantages of traditional boundary element method, but also solves the problem of dependence on meshes and low accuracy of interpolation function in BEM. With the help of virtual boundary, the method effectively avoids the problems of singular integral and boundary effect which are associated with other boundary type numerical methods. What’s more, through the choice of round virtual boundary, the method completely avoids the dependence on meshes, so it is a real meshless boundary type method. The results show that the method has higher accuracy than traditional BEM.

Key words： Radial basis function(RBF) virtual boundary boundary element method (BEM) meshless method
