Abstract: In this paper, the near-to-far field transformation is proposed to predict the far fields of metamaterials from the near-field measureddata, which can be achieved by two-dimensional (2D) near-field microwave scanning apparatus (2D mapper). The 2D mapper is a near-field scanning system, from which the far-field data cannot be obtained directly. The near-to-far field transformation method has been studied to predict the far fields from the known near-field information, which will make the 2D mapper more efficient in the measurement of metamaterials. The correctness and feasibility of the proposed transformation are verified by both numerical simulations and experiments.
Keywords: Metamaterials, Near-field scanning system, Far-field prediction.
