In this paper we computed the characteristic impedance of
homogeneous Striplines with finite or infinite dielectric substrate,
using the Finite Differences Method (FDM) and Spatial
Compression (CE), with transformation functions found through
Genetics Algorithms (GAs). The CE consist on the
transformation of any plane transmission line domain with very
different dimensions, in a rectangle in which the images of the
dimensions maintain proportions that make easier the FDM
application in an efficient way, without supposing that the
dielectric substrate is infinite. The coefficients of the
transformation were found using GAs. We obtained
Characteristic Impedance values for lines with different relations
of dimensions and for finite or infinite dielectric substrates. The
results were compared with results found in the literature,
obtaining good agreement.
