1. A device for controlling radiofrequency beams, comprising a set of at least one cell, said cell comprising a support frame and at least one interconnection internal to said support frame, said radiofrequency beams being TEM electromagnetic waves having a given polarization, wherein said support frame is inscribed within a general shape of a prism, having a given axis Z′, said prism comprising N faces Pn connected to one another by N edges An, oriented along the axis of the prism Z′, said support frame comprising N corner elements, each corner element having a rim coincident with one of said edges of the prism, the corner elements being arranged such that the support frame has, on each face of the prism, a slot extending along the axis of the prism Z′, said support frame being interrupted by said slots; and
in that each internal interconnection comprises N inductive rods each comprising two ends, the inductive rods each having a first end connected to one of said rims of the support frame, the second ends of the inductive rods being connected to one another at a rod connection point, said rod connection point being positioned substantially in the centre of said support frame in a plane orthogonal to the axis of the prism Z′,
each cell being configured to carry out polarization-invariant transmission and/or reflection of radiofrequency beams of said TEM electromagnetic waves.
