Abstract
A system for detecting receivers including at least one receiver, a container having a volume for containing the receiver, an antenna suitable for emitting a primary wave in the volume and for receiving a secondary wave emitted by the receiver in the volume in response to reception of the primary wave, and a controller suitable for controlling the emission of the primary wave and for detecting the receiver via the received secondary wave. The system further includes adjustable elements controlled by a control wave, attached to the container and having an impedance that can be modified. Each adjustable element includes a device for recovering energy from the primary wave and/or from the control wave in order to power itself, and a device for receiving the control wave which decodes an adjustment parameter so that the adjustable element controls its impedance.
