Abstract :
A modified multiresolution time domain method (MRTD) is presented. The numerical dispersion of the modified MRTD is studied. The results show that the spurious solution that found in the original MRTD of Krumpholz and Katehi (see IEEE Transactions on Microwave Theory and Technique, vol.44, no.4, p.555-71, 1996) has been successfully removed.
