Hybrid space discretizing-integral equation methods for numerical modelingof transient interference

The application of hybrid time-domain transmission line matrix (TLM)-integr al equation (TLM-IE) methods is discussed. The hybrid TLM-IE methods are su ited very well for the numerical modeling of the electromagnetic interactio n between complex objects separated by large free-space regions, While the held inside the objects is modeled by the TLM method the electromagnetic in teraction between the objects is described via Green's functions. The hybri d methods are applied to analyze the near-field coupling of two shielded en closures, In a final discussion, the hybrid methods are compared with each other and with the pure TLM method, especially considering the computationa l time and storage requirement. Compared with the pure TLM method the hybri d methods require a considerably reduced computational effort.
