Wavelet method in the solution of magnetic field integral equations

The wavelet method is applied for the solution of magnetic field integral equations, where the impedance matrix arising in the solution is sparsified and divided into four submatrices, and then the induced current is obtained by the iteration method. It is shown by numerical experiments that the computing time of this method is dramatically reduced compared to conventional methods, such as the method of moments hybridised with physical optics in radar cross-section computation.
