Comparative analysis between 3D-TLM Nodes in the frequency domain
This paper presents a comparative analysis of the numerical dispersion of 3D FD-TLM (Frequency Domain Transmission Line Matrix) nodes. Three principal nodes are considered for this analysis: The Symmetrical Condensed Node (SCN), The Hybrid Symmetrical Condensed Node (HSCN) and the Super Symmetrical Condensed Node (SSCN). Numerical results are obtained for a rectangular waveguide with dielectric discontinuity. Both cubic and parallelepiped meshes were used to model the structure. It has been found that characteristics of those nodes depend on the cell aspect ratio and their performances seem to confirm those found with TD-TLM (Time Domain Transmission Line Matrix).
