Abstract: A device for controlling radiofrequency beams of a given polarization, the device includes a set of at least one cell, comprising a support frame and at least one interconnection internal to the frame. The frame is inscribed within a prism, having a given axis Z? and faces connected to one another by edges oriented along the axis Z?. The frame comprises corner elements, each having a rim coincident with an edge and being arranged such that the frame has, on each face, a slot (440-n) extending along the axis Z?. The interconnection comprises inductive rods, each comprising two ends of which a first end is connected to a rim, the second ends being connected to one another at a connection point positioned in the centre of the frame in a plane orthogonal to the axis Z?. Each cell is configured to carry out polarization-invariant transmission and/or reflection of beams.

Abstract: Quartz is a variety of winter oilseed rape that arose from a long-term breeding program focused on key output traits of (1) winter survival, (2) seed yield and (3) financial return for farmers in this order. Breeding objectives were restricted to these 3 so as these traits could be quickly identified.

Abstract: The invention concerns a floor making it possible to circulate between two vehicles connected together by an articulated connection. The floor according to the invention includes a first deck fixed to the end of one of the vehicles and a second deck fixed to the end of the other vehicle. These two fixed decks are each partially covered by a movable deck, and are connected to each other by two deformable members including links and connecting rods. The movable deck is thus guided kinematically by the deformable parallelogram during the movements of the vehicles, notably when going round bends.
