摘要：

We report the design of a metamaterial-based antenna beamformer that transforms 7 stipulated inputs to 7 prescribed output beams. The beamformer is printed and exhibits a broad bandwidth of operation. It is modeled as an inhomogeneous, anisotropic 2D medium, and is designed using an constrained optimization approach. This design technique offers improved flexibility and feasibility over coordinate transformation methods. The constitutive parameters of the beamformer are implemented using printed-circuit metamaterials. Measurement results for the fabricated beamformer are presented and show excellent agreement with the design goals.
