Radome for vehicles
The radome (10) for vehicles comprises a substrate (18) formed of a radio transmissive resin, the substrate (18) having a proximal face and a distal face and a decoration layer (20) applied to the proximal face, the decoration layer (20) comprising a metalloid or a metalloid alloy deposited on the surface of the proximal face, wherein said metalloid or metalloid alloy is combined with at least one oxide. It improves the metalloid decoration layer adhesion on the substrate and its corrosion resistance.
Metasurface-assisted 3D beam shaping for desired phase, amplitude, and polarization
Cascaded metasurfaces can control the phase, amplitude and polarization of an electromagnetic beam, shaping it in three dimensional configuration not achievable with other methods. Each cascaded metasurface has dielectric or metallic scatterers arranged in a period array. The shape of the scatterers determines the three dimensional configuration of the output beam and is determined with iterative calculations through computational simulations.
Cover element
A cover element is provided for a radome in a vehicle, which has an at least partially metallised film which is over-moulded on a front side with a layer of a first plastic and back-moulded on a back side with a cover layer of the second plastic, wherein a heating element is provided on the back side or front side of the at least partially metallised film.
