Claim 7:
8. A metalens transmitting light to a multi-point design pattern, the metalens comprising:
an integrated planar structure configured to focus light into a multi-point focused design pattern, wherein the multi-point design pattern is created using a plurality of phase shifters configured according to the following phase profile equation:, Φ
