E. Drake et al., QUASI-ANALYTICAL STATIC SOLUTION FOR THE GENERALIZED BOXED COPLANAR WAVE-GUIDE, International journal of microwave and millimeter-wave computer-aided engineering, 4(2), 1994, pp. 163-174
A quasi-analytical method rawer computing the quasi-static-TEM paramet
ers of the generalized roe waveguide (GCPW) is reported. The structure
is assumed to be enclosed in a rectangular frame and embedded in a la
yered medium. Essentially, the method is an analytically enhanced spec
tral domain formulation. Its application leads to virtually exact resu
lts in very short CPU times, making it suitable for CAD purposes. Alth
ough the method is somewhat more time consuming than conformal mapping
approaches, it is a useful alternative because of its exactness and a
bility to deal with multilayer structures. (C) 1994 John Wiley & Sons,
