Transmittable Nonreciprocal Cloaking

Abstract
Offering a potential pathway to the fantasy of invisibility, cloaking has been a most popular concept since its introduction over 15 years ago. This article furthers the concept by making the cloak transmittable, so as to allow ``transmitting without being seen''. This special cloak consists of a concentric set of bianisotropic metasurfaces with a nonreciprocal innermost element, and allows the entity sitting at its center to transmit information at will in a desired direction while remaining invisible in all other directions. Such cloaks may find application in e.g. stealth technology, blockage avoidance, optical illusion, and cooling.
