Published in 2013

A novel type of tunable surface acoustic waves (SAW) filter based on 1D phononic crystal controlled by electric is field proposed. The tunability of proposed filter varied over a wide range: 1-20%. Basic idea is electrical controlled induced periodical domains in ferroelectric film based on induced piezoelectric effect.
