QUICK QUASI-TEM ANALYSIS OF MULTICONDUCTOR TRANSMISSION-LINES WITH RECTANGULAR CROSS-SECTION

This paper presents an efficient and accurate procedure for computing the quasi-static matrix parameters ([C], [L], [G], and [R]) of rectang ular-shaped conductors embedded in a multilayered dielectric medium ov er an infinite ground plane. An additional top ground plane can also b e considered, The problem is formulated in terms of the space-domain i ntegral equation for the free-charge distribution on the slab conducto r surfaces, The spatial Green's function is computed from its spectral counterpart using system identification techniques [Prony's method or matrix pencil method (MPM)]. The integral equation is solved by means of a Galerkin scheme employing entire domain basis functions, This re sults in a small matrix size. In addition, the quasi-analytical evalua tion of the entries of the Galerkin matrix leads to a very efficient a nd accurate computer code, A detailed study on the convergence and acc uracy of the method has been included.
