Abstract
Subject headings
Close
- A lens (300, 500) is disclosed for steering the exit direction (Ω) of an incident electromagnetic wave. The lens comprises a main body (210, 510) of a ferroelectric material with a first main surface (207, 507) and a first transformer (220, 222). The electromagnetic wave enters and exits the lens through the transformer, and the lens comprises means (370, 380) for creating a DC-field in a first direction in the main body. The main body (210, 510) of ferroelectric material comprises a plurality (21011-210NN, 51011-510NN) of slabs of the ferroelectric material, each slab also comprising a first (403, 603) 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
