Analysis of millimeter waveguides on anisotropic substrates using the three-dimensional transmission-line matrix method

The Application of the Supercondensed TLM Node to Propagation Problems in Inhomogeneous Anisotropic Materials

“…2b. They are found to be in excellent agreement with the results obtained using other analytical and numerical techniques [2,3].…”

“…Transmission-Line Modelling (TLM) method [1] has been applied successfully to many electromagnetic wave propagation problems including complex anisotropic media [2,3]. Accurate modelling of these problems usually requires finer mesh within the anisotropic substrate and use of cells with arbitrary aspect ratio suitable for modelling particular geometrical features.…”
