The electrically tunable lens based on nonlinear ferroelectric materials (Ba0.4 Sr0.6 Ti O3 ) for deflecting of the microwave (MW) beam is presented. The distinctive feature of the deflector is the use of multilayer periodic structure FE/LD/FE/LD/. . ./FE (FE-ferroelectric, LD-linear dielectric) with transparent for MW signal electrodes. Simulation and experiments demonstrate that periodic structure provides the slow wave propagation effect, that in turn results in the increase of effectiveness of lens operation. At frequency ∼ 30 GHz the lens provides scan angle α ∼ ±20 deg.
