In this proof-of-concept analytical study (supported by numerical examples) the authors are able to achieve controllable enhancement of the electrostriction in a metamaterial medium consisting of an array of spheres in a host medium. Accounting for material dispersion and losses for a few test cases, they show a sizable enhancement (or suppression) and tunability of the electrostrictive properties. We anticipate that this study will open interesting directions previously unexplored in metamaterials research.

Polar zinc titanate (ZnTiO) is a promising lead-free ferroelectric compound with high spontaneous polarization of 75 , which is comparable with that of PbTiO. In this work a collaboration of researchers from Germany, UK, and USA present a detailed investigation of vibrational properties of ZnTiO via the high-pressure Raman spectroscopy, second-harmonic generation, and calculations.
