Abstract

In electrical engineering metamaterials have been developed that offer\nunprecedented control over electromagnetic fields. Here we show that general\nrelativity lends the theoretical tools for designing devices made of such\nversatile materials. Given a desired device function, the theory describes the\nelectromagnetic properties that turn this function into fact. We consider media\nthat facilitate space-time transformations and include negative refraction. Our\ntheory unifies the concepts operating behind the scenes of perfect invisibility\ndevices, perfect lenses, the optical Aharonov-Bohm effect and electromagnetic\nanalogs of the event horizon, and may lead to further applications.\n
