A method of altering properties in a ferroelectric material having a dielectric constant epsilon r, a loss tangent tan delta , and tunability at a given frequency f, comprising reducing said dielectric constant epsilon r and said loss tangent tan delta while preserving a substantial fraction of said tunability, provides structures (21) of said ferroelectric material that are essentially one- or two-dimensional, said structures (21) oriented such that at least one dimension is parallel to a direction of applied dc bias field. <IMAGE> |
