Analysis of Elliptic and Cylindrical Striplines Using Laplace´s Equation

Analysis of elliptic and cylindrical striplines based on Laplace´s equation is presented. The solution of boundary value problem is obtained by an application of the modified residue calculus technique. The numerical results on the characteristic impedance are presented for a wide range of parameters. From the series solution of the Laplace´s equation, the potential distribution is determined. The effect of warpage due to environmental changes on an otherwise planar structure is also estimated.
