A compact 2-D full-wave algorithm using weighted Laguerre polynomials for exact attenuation constant extraction of lossy transmission lines

A compact 2-D marching-on-in-order method combined with the complex variable technique is applied to extract accurate attenuation constant of lossy transmission lines. In the time domain, the weighted Laguerre polynomials and the Galerkin temporal testing procedure are adopted to construct the marching-on-in-order equations. Moreover, it is computationally much more efficient than conventional FDTD method. In the space domain, we apply the complex variable technique rather than the real variable technique. And then, the whole three steps of an iterative process are applied to extract accurate attenuation constants of lossy transmission lines
