Gg. Gentili, AN INVESTIGATION ON THE EFFECT OF UNDERCUTTING ON THE PROPAGATION PARAMETERS IN SINGLE AND COUPLED QUASI-TEM LINES IN A MULTILAYERED DIELECTRIC, International journal of microwave and millimeter-wave computer-aided engineering, 5(6), 1995, pp. 406-413
The effect of undercutting on the electrical parameters of general sin
gle and coupled quasi-TEM lines in a multilayered dielectric is studie
d by an efficient quasistatic numerical method. Results are presented
for characteristic impedance, propagation constant, and attenuation co
nstant in single lines; two symmetrical coupled lines; and a four-line
system, In all cases studied a significant increase of losses has bee
n observed. (C) 1995 John Wiley & Sons, Inc.
