The article presents a computational method for calculating the electr
ic potential and field distributions in a coupled coplanar waveguide w
ith finite electrode thickness. This method provides a simple and fast
approach to the quasistatic analysis of the structures. The same stru
cture with infinitely thin electrodes is also analyzed using conformal
-mapping techniques, and excellent agreement of the results is obtaine
d between the two methods. (C) 1995 John Wiley & Sons, Inc.
