An Efficient Numerical Technique to Predict Phase Responses of Reconfigurable Reflectarray Cells with Mutual Coupling

International audienceThis paper presents a numerical technique to predict realistic phase responses of active cells within a reflectarray. The phase responses of an active cell are determined as a function of the states of the neighboring cells. The phase probability distributions are computed and realistic phase responses are then evaluated. A synthesis application is presented in order to highlight the interest of the realistic phase responses
