New method for measuring properties of ferroelectric materials in microwave

Over the last few decades, ferroelectric materials have been gaining much interest due to the unique operational characteristics they demonstrate when a dc electric field is applied. This paper is committed to introduce a new way of investigating ferroelectric materials and their characteristics under the effect of an electric field bias (about 1000V)and high frequencies (0.8GHz~1 GHz). In the new method, TRL calibration and an electric field bias is invoked to guide the microstrip line. Meanwhile, simulation and measured results demonstrate the effectiveness of the scheme.
