Abstract :
A method for determining the electromagnetic properties of Ba0.7Sr0.3TiO3 (BST) thin films is presented in this paper. At first we introduce a broadband characterization method based on the extraction of the intrinsic properties of a substrate from the measurement of a kit composed of five coplanar waveguides and then we employed an accurate on wafer TRL calibration technique to measure the permittivity of the BST thin film.
