After giving historical data on FDTD speed and problem sizes, the state of the art approach to fast and efficient FDTD simulations is explained for large scale structures. Future challenges include the simultaneous simulation of the RF device or antenna and its surrounding environment, increasing the modeling effort by at least an order of magnitude. An intelligent hierarchical concept exploiting...
This paper investigates the influence of the grid density, i.e. the amount of nonnegligible wavelet coefficients (Haar) used to represent the electromagnetic field, on integral parameters, like scattering parameters. A band-stop filter based on an unbalanced composite right/left-handed transmission line (CRLH-TL) is the specific example evaluated. The TL-based metamaterial (MTM) has been simulated...
