Abstract :
This paper introduces an improved TLM analysis method for full-wave analysis of arbitrary guiding structure. In contrast to the conventional TLM full-wave analysis, this new method is based on a novel TLM node and only requires two dimensional mesh and the whole dispersive and attenuation characteristic can be obtained in one run of calculation. This leads to a significant reduction in CPU time and memory space, and makes the TLM method an even more attractive tool in the analysis of arbitrary guiding structures. Numerical results are given for rectangular waveguide filled with lossy dielectric, shielded image line composed of lossy dielectric and microstrip line with lossy conductors, lossy substrate and finite metallization thickness.
