Rb. Tsai et Kl. Wong, CHARACTERIZATION OF CYLINDRICAL MICROSTRIPLINES MOUNTED INSIDE A GROUND CYLINDRICAL SURFACE, IEEE transactions on microwave theory and techniques, 43(7), 1995, pp. 1607-1610
A full-wave analysis for the frequency-dependent characteristics of a
cylindrical microstripline mounted inside a ground cylindrical surface
is presented. Numerical results of the effective dielectric constant
and characteristic impedance for various microstripline parameters are
calculated and analyzed. Strong dispersive behavior is observed for s
uch cylindrical microstriplines.
