Optimal polarization conversion in coupled dimer plasmonic nanoantennas for metasurfaces
We demonstrate that polarization conversion in coupled dimer antennas, used in phase discontinuity metasurfaces, can be tuned by careful design. By controlling the gap width, a strong variation of the coupling strength and polarization conversion is found between capacitively and conductively couple...
