A New Approach Combining Surrounded-Element and Compression Methods for Analyzing Reconfigurable Reflectarray Antennas

An efficient technique to provide fast and accurate analysis of large-scale and complex reconfigurable reflectarray antennas is presented and validated. The method combines the surrounded cell approach and the compression technique to analyze the global array. It takes into account the mutual coupling effects and the numerical complexity is reduced. Only a minor electromagnetic simulation and a fast post-processing are required.
