Abstract: We demonstrate a controllable enhancement in the electrostrictive properties of a medium using dilute composite artificial materials. Analytical expressions for the composite electrostriction are derived and used to show that enhancement, tunability and suppression can be achieved through a careful choice of constituent materials. Numerical examples with Ag, As$_2$S$_3$, Si and SiO$_2$ demonstrate that even in a non-resonant regime, artificial materials can bring more than a threefold enhancement in the electrostriction.<br />Comment: 8 pages, 5 figures, to appear in Physical Review B
