| Abstract: | A multiresolution scheme for discretization of electromagnetic integral equation and boundary element equation is presented. The method discretizes the body by relatively coarser scaling functions and introduces the wavelet functions to acquire higher precision step by step. This method is the same as direct discretization with higher resolution scaling functions. The derived matrix is sparse because of its sparsity prescribed in advance, and the storage requirement is greatly reduced. Comparing this scheme with the Moment Method and zero order Boundary Element Method, the result shows that the scheme is more reasonable. |
