Abstract

In this paper, an improved two-dimensional finite-difference time-domain (2-D FDTD) model has been proposed for extracting the attenuation constant of the uniform lossy transmission line. Compared with the reported methods, the developed model is reliable and precise and the precise result can be achieved fast. As an example, the attenuation constant of a lossy microstrip line is extracted to perform the proposed method. The unique characteristic comes from the automatic convergence ability of the improved 2-D FDTD model.
