- Abstract
Experimental measurements of coplanar waveguide circuits atop thin films of ferroelectric BaxSr1-xTiO3 (BST) were made as a function of dc bias from 0 to 200 V and frequency from 0.045 to 20 GHz. The resulting phase shifts are compared with method-of-moments electromagnetic simulations and a conformal mapping analysis to determine the dielectric constant of the BST films. The accuracy of the resulting dielectric constants is analyzed and compared to low-frequency measurements of interdigitated capacitor circuits on the same films. © 2001 John Wiley & Sons, Inc.
