A novel hybrid method combining the flexibility of transmission line matrix method and the efficiency of time domain method of moments is presented for the efficient analysis of radiating structures in presence of obstacles located within the propagation environment. While the field inside the complex in-homogeneous objects is modeled by the TLM method, conducting thin wire, surface structures and the free-space electromagnetic interaction between the objects are described via time-domain integral equations. The proposed hybrid method is applied to analyse the near-field coupling of a patch antenna with obstacles represented by an apertured metallic enclosure and a thin wire. To validate this new approach, we have compared the results with those obtained using the pure transmission line matrix method.     «
