Abstract

This paper presents a novel method for surface impedance characterization for a metasurface with printed elements and arbitrary geometry. The modeling of the metasurface as a surface impedance simplifies the entire design cycle of a multilayer metasurface structure and enables analysis using transmission line theory. The proposed method is compared to HFSS simulations and very good agreement was obtained. Using the proposed model, a flat lens antenna based on a multilayer metasurface structure with printed elements that locally corrects the phase has been designed. The performance of the proposed lens in terms of radiation pattern and gain is satisfactory.
