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.
