Apparatus for radar target cloaking using polyhedral conducting mesh

NRL

An apparatus for interfering with and canceling electromagnetic reflections from a conducting object such as a solid or hollow conducting sphere. The reflection of an incident electromagnetic wave from a conducting sphere can be reduced or cancelled by placing a polyhedral conducting mesh (PCM) around the conducting sphere. The incident EM wave induces electric fields in the region between the conducting mesh and the internal conducting sphere. These induced electric fields may interfere with and in some cases may completely cancel the incident EM wave and thus reduce reflection. The PCM can be tuned to reduce or cancel reflection of incident EM waves at one or more specific frequencies.
