  • Abstract
    A new multiresolution approach for the FDTD is proposed and applied to an ultra wide-band (UWB) problem. The multiresolution FDTD with switchable grid (SWG-FDTD) splits the simulation along the time into two FDTD schemes with different mesh densities. The fist part of the simulation is carried out using fine mesh in order to take into account the strong near-field variations. The second part of the SWG-FDTD simulation uses a coarse mesh to finish the simulation. In our example, it enables a 60 % gain in computation time while maintaining good accuracy on the results.
