The conjunction with space coordinate transformation has led to a novel \"relativity inspired\" approach for the control of light propagation. \"Invisibility cloak\" is the most fascinating proposed devices3,4. However, the realized structures up to now used a graded \"metamagnetic\" so as to achieve the cloaking function11. Artificial magnetism is however still very challenging to obtain in optics despite the currently promising building blocks13-17, not suited for optical cloaking.
