Abstract :
A frequency-domain 2D full wave method is presented in this paper for extracting frequency-dependent equivalent circuit parameters R, L, G and C of any mode in a guided wave structure. The parameters extracted by this method can be used in circuit simulators to investigate frequency-domain responses of the transmission lines which are uniform along the wave propagation direction. Because a compact 2D lattice is used instead of the conventional Yee´s 3D lattice, and calculations are performed only on the cross-section of a structure, computation expenditures are reduced significantly. In addition, it can account for any arbitrary geometry and any guided-wave mode. Numerical examples are provided to validate the method.
