APPLICATION OF THE TRANSMISSION-LINE MATRIX-METHOD TO THE ANALYSIS OFSCATTERING BY 3-DIMENSIONAL OBJECTS

The transmission line matrix (TLM) method is applied to the analysis o f electromagnetic scattering from finite-sized conducting and dielectr ic objects. The TLM method is a general numerical method for obtaining an approximate solution to the time-dependent form of Maxwell's equat ions in the presence of geometrically complex environments. The three- dimensional symmetrical-condensed TLM node together with a total/scatt ered field formulation and a local absorbing boundary condition are ap plied, Numerical results for a variety of conducting and dielectric ob jects demonstrate the accuracy of the method, Various guidelines for t he successful application of the method to this class of problem are p rovided.
