We have studied voltage‐tunable (0–200 V) broadband (0.1–5.1 GHz) microwave properties at room temperature and the liquid nitrogen temperature of two coplanar waveguide devices made from a Au / Sr 0.5 Ba 0.5 TiO 3 bilayer and a YBa 2 Cu 3 O 7‐x / SrTiO 3 bilayer, respectively. The experimental results agree well with the predictions of simple quasistatic and quasi‐TEM models. © 1995 John Wiley & Sons, Inc.
