Abstract: In one example in accordance with the present disclosure, a system is described. The system includes at least one directional antenna to 1) emit energy waves towards a mass in which an object is disposed and 2) receive reflected signals from a resonator disposed on the object as the mass is moved relative to the directional antenna. The system also includes a controller to, based on received reflected signals, determine a pose of the object within the mass.

Abstract: Examples disclosed herein relate to a layered RFID tag. In one implementation, a layered passive chipless RFID tag includes a first conductive layer, a second dielectric layer, and a third conductive layer. The first, second, and third layers may be in a stacked configuration with the second layer between the first layer and the second layer.
