Abstract
A device capable of enhancing an electric field to drive an electromagnetic tag into operation is switchable between states to control operation of the tag. Enhancement is provided by a dielectric cavity structure defined between first and second conducting layers. Different states of the device may have different resonant frequencies and read ranges according to the characteristics of the enhancement. As such a container can be provided which includes a tag which switches states on opening, allowing improved tracking characteristics.
