Hiding an elephant into a matchbox with transformation optics

Based on transformation optics‎, ‎we propose an illusion device that can make‎ ‎objects look much smaller and different than they actually are‎. ‎In particular‎, ‎the device has a capability to hide a large object (like an elephant) into a‎ ‎small one (like a matchbox)‎. ‎Compared to previous proposals for illusion‎ ‎devices‎, ‎there is no requirement for negative refractive index or for speed of‎ ‎light going to infinity as in Euclidean invisible cloaks‎. ‎We demonstrate the‎ ‎functionality of the device by full wave simulations‎.
