Abstract :
A number of publications have demonstrated that the application of the method of moments directly to Maxwell´s equations allows for the use of multiresolution analysis in the time domain. The principles of multiresolution analysis are applied to derive a novel multigrid scheme for the finite difference time domain (FDTD) technique. For the first time in literature, a mathematical correct approach for this problem is presented which allows for a priori estimation of the error. A dispersion analysis illustrates the benefits of additional wavelets in the FDTD analysis.
