Abstract

This study shows recent results in the implementation of electrically reconfigurable structures based on sub-wavelength resonators implemented by means of ferroelectric materials. Barium-Strontium-Titanate thick films are employed as part of the substrate to implement electrically tunable split-ring resonators and open complementary split-ring resonators. Different structures have been fabricated proving the viability of this strategy for the implementation of reconfigurable structures. The achieved frequency shift reaches 12.6%. A parameter extraction method has been applied to study the effects of the modification of the dielectric permittivity of the ferroelectric material on the structure properties and its frequency response.
