Design of an integrated lens for separating microwave and optical wave

An integrated lens was designed, which is composed of an optical Fresnel lens (OFL) and a microwave helix array (MHA). The OFL focuses the incident light wave while the MHA focuses on the incident microwave. The MHA has little effect on blocking incident light while the OFL has effect on microwave transmission. The proposed integrated lens can simultaneosly focus microwave and optical wave on two different spots, and the distance between them is 35cm. The intensity of the electric field has a 5-fold improvement at the microwave focus. So it can transmit and receive microwave signal on the basis of the full use of the incident visible light when the integrated lens is uploaded.
