The contributions in this thesis address the theoretical concept and the numerical application of the novel hybrid TLMIE/TDMOM method combining the flexibility of Transmission Line Matrix method (TLM) with the efficiency of the Integral Equation / Method of Moments for the efficient numerical modeling of transient interference between complex objects, separated by large free-space regions. The complex inhomogeneous object is embedded into a closed TLM-subregion and modeled by the transmission line matrix (TLM) scheme. Free-space regions, curved conducting thin wires and surfaces can be efficiently modeled by the time domain Method of Moments (TDMOM). The application of the equivalence principle allows us to divide the three-dimensional space into subregions, and to apply each method in its best domain of application. The attributes of such methods, both in terms of computational efficiency, solution accuracy and stability, are examined through their application to the analysis of typical electromagnetic problems.
