Abstract:

An attempt to establish analogy between the antenna array pattern synthesis theory and the metasurface beam-steering control is presented in this paper. Beam steering has been achieved by using a phase transformation metasurface, and the side-lobe level (SLL) reduction has been achieved by optimizing the excitation amplitude of feed array. Optimization has been performed by a simple evolutionary approach based on cross-entropy (CE) method, and the results validate the efficiency of the algorithm, as well as verify the concept of SLL control using excitation amplitude manipulation.
