    • A method for determining the topography of a static surface (305) of an object (301) comprises the steps of: (a) selecting a region (301a) on the static surface (305) of the object (301); (b) directing an incident monochromatic electromagnetic wave (302) onto the region (301a) while the surface (305) and the incident monochromatic electromagnetic wave (302) are moved relative to one another, the incident monochromatic electromagnetic wave (302) being characterised by a frequency f 0 , an amplitude A 0 and a propagation direction, the direction of movement (304) being substantially not parallel to the propagation direction of the incident monochromatic electromagnetic wave (302), wherein the surface (305) reflects the incident monochromatic electromagnetic wave (302) thus generating a reflected monochromatic electromagnetic wave (303), the movement (304) being characterized by a movement frequency (F) and a movement amplitude (A); (c) determining properties of the monochromatic electromagnetic wave (303) reflected from the region (301a) during the movement (304); and (d) analyzing properties, e.g. frequency f 0 , of the incident monochromatic electromagnetic wave (302) and the properties, e.g. frequency f r , of the reflected monochromatic electromagnetic wave (303) to obtain information about the topography of the region (301a) of the object (301). A corresponding system is also provided.

    • 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.
