The application of hybrid time-domain transmission line matrix (TLM)-integral equation (TLM-IE) methods is discussed. The hybrid TLM-IE methods are suited very well for the numerical modeling of the electromagnetic interaction between complex objects separated by large free-space regions. While the field inside the objects is modeled by the TLM method the electromagnetic interaction between the objects is described via Green's functions. The hybrid methods are applied to analyze the near-field coupling of two shielded enclosures. In a final discussion, the hybrid methods are compared with each other and with the pure TLM method, especially considering the computational time and storage requirement. Compared with the pure TLM method the hybrid methods require a considerably reduced computational effort
