G. Ghione et M. Goano, A CLOSED-FORM CAD-ORIENTED MODEL FOR THE HIGH-FREQUENCY CONDUCTOR ATTENUATION OF SYMMETRICAL COUPLED COPLANAR WAVE-GUIDES, IEEE transactions on microwave theory and techniques, 45(7), 1997, pp. 1065-1070
Closed-form CAD-oriented conformal-mapping approximations are presente
d for the HF attenuation of two-conductor symmetrical coupled coplanar
waveguides (CCPW's). The expressions are compared with the results ob
tained from a full-wave electromagnetic (EM) simulator and found to yi
eld acceptable agreement, A modified form is also presented according
to [1], which partly overcomes the low-frequency limitations of the sk
in-effect approximation.
