Abstract :
Among the solutions allowing one to design frequency agile microwave devices, Y-Ba-Cu-O/Sr-Ti-O//La-Al-O multilayers can be used to obtain a frequency shift of 10% and individual resonator Q0 higher than 1000. A resonator used for the extraction of the material characteristics and as a single clement filter was optimized. The filter design allows the control of the response over the frequency range. Stop-band filters were tested with good agreement between the materials properties and the modeling
