Abstract
Embodiments of the present invention relate to a chaff electronic countermeasure device. The device comprises an antenna that is in communication with a substrate. An integrated circuit is in electrical communication with the conductive antenna element. The conductive antenna element includes a conductive composition. The conductive composition includes a conductive polymer and graphene sheets. The device is configured to absorb from a radar source a first radio frequency having a first amplitude. The device is configured to absorb from a radar source a first radio frequency having a first amplitude. In response to absorbing the first radio frequency, the device is configured to reradiate at least a portion of a second radio frequency having a second amplitude toward the radar source, which results in an increased radar cross section of the device as perceived by the radar source. The second amplitude is higher than the first amplitude.
