Abstract
In this paper, a polarization re-configurable meta-surface is proposed and verified. It is composed of split-ring-resonators (SRRs) including a pair of splits in each SRR and re-configurability is achieved using PIN diodes. It is printed on an FR4 dielectric substrate supported by a metallic ground plane in its backside. The ON/OFF combinations of four PIN diodes connected between the splits result in polarization re-configurability. The proposed meta-surface produces polarization conversion for the reflected wave when all four PIN diodes are in the OFF state. But, when the PIN diodes are in the ON state, there will be no polarization conversion for the reflected wave. The performance of this proposed meta-surface is very simple to implement and is designed in the frequency range 5.71- 10.72 GHz. Also, a study of polarization conversion for different angles of incidence are conducted and an almost stable performance is observed.
