A lens () is disclosed for steering the exit direction (&#x3a9;) of an incident electromagnetic wave. The lens comprises a main body () of a ferroelectric material with a first main surface () and a first transformer (). The electromagnetic wave enters and exits the lens through the transformer, and the lens comprises means () for creating a DC-field in a first direction in the main body. The main body () of ferroelectric material comprises a plurality (-NN,-NN) of slabs of the ferroelectric material, each slab also comprising a first () and a second electrode of a conducting material. The means for creating a DC-field can create a gradient DC-field in the first direction using the first and second electrodes, so that the dielectric constant in the main body will also be a gradient in the first direction, thus enabling steering of the existing electromagnetic wave.
