Abstract: The near field meta-molecular interactions in a lattice play an important role in determining the collective behavior of the metamaterials. Here, we exploit the nearest neighbor inter unit cell interactions and the intra near-field coupling in metamolecules to manipulate the co- and the cross-polarized light. We observed large enhancement in the bandwidth and the amplitude of the transmitted light in the strongly coupled meta-molecular lattice. We further show that the proposed metasurface could function as a broadband achromatic quarter-wave plate. The chosen meta-molecular design also enhances the cross-polarized light when integrated with a ground plane to operate in the reflection mode.
