Abstract
The invention relates to a metasurface lens using a planar array of elementary resonators, each elementary resonator being the shape of a cross the arms of which are of unequal length. The phase shift applied by an elementary resonator is dependent on its orientation in the plane of the lens, the orientation of the various elementary resonators being determined depending on the shape of the desired wavefront. Such a lens has a substantially uniform transmission-coefficient distribution and a low chromatic aberration. Furthermore, it has a very good spectral selectivity.
