Abstract :
This paper reports the development of a new symmetrical condensed TLM node derived directly in the frequency domain. The new node can accommodate a graded mesh and can model lossy anisotropic media described by a static conductivity tensor along with complex permittivity and complex permeability tensors. The frequency domain TLM method is used to generate modal dispersion curves for microwave and millimeter wave guiding structures. The results compare the new node to existing time domain symmetrical condensed nodes.<>
