Metamaterials presenting a high circular dichroism are highly sought for various possible applications. Geometries in literature present the choice between complex elaborate geometries and shallow performances. In this work, we introduce a new planar geometry for a plasmonic metamaterial array featuring a high CD over a large bandwidth. We present the details on the related design methodology and fabrication procedures. During design step, shape variations around the perfect values have also been simulated and taken into account, and the performance are robust. The planar geometry helps not only to simplify the fabrication processes, which makes it more accessible for various applications, inexpensive and industrially feasible.
