Now the concepts of cloaked sensing and cloak detection are being extensively studied [17–19]. In this work we propose a scheme for watching the outside while hiding under a carpet cloak based on transformation optics. Unlike conventional carpet cloaking, which screens all the incident electromagnetic waves, we break the cloak
