Abstract: Metamaterial particles having active electronic components are disclosed. According to one aspect, a metamaterial particle in accordance with the subject matter disclosed herein can include a field sensing element adapted to sense a first field and adapted to produce a sensed field signal representative of the first field in response to sensing the first field. Further, the metamaterial particle can include an active electronic component adapted to receive the sensed field signal and adapted to produce a drive signal based on the sensed field signal. A field generating element can be adapted to receive the drive signal and adapted to produce a second field based on the drive signal.
