Configurable electromagnetic reflector

摘要

Configurable passive electromagnetic reflectors are disclosed, as are aircraft comprising configurable passive electromagnetic reflectors and methods to use configurable passive electromagnetic reflectors. In one embodiment a system comprises a reflector comprising a surface having a plurality of addressable patches switchable between a reflective state and a non-reflective state, and a controller coupled to the reflector to provide signals to switch the plurality of addressable patches between the non-reflective state and the reflective state to configure the reflector to selectively reflect incident electromagnetic radiation toward a remote target. Other embodiments may be described.

1. A system, comprising:
a reflector comprising a surface having a plurality of addressable patches switchable between a reflective state and a non-reflective state; and a controller coupled to the reflector, the controller configured to:
determine a frequency and a direction of incident electromagnetic radiation;determine a reflector configuration to reflect the incident electromagnetic radiation to a remote target; andprovide signals to switch at least a portion of the plurality of addressable patches between the non-reflective state and the reflective state to configure the reflector to reflect the incident electromagnetic radiation to the remote target based on the reflector configuration.
