Description
Summary:In this paper, we introduce the metasurface (MS) designed to generate Orbital Angular Momentum (OAM) within the 5.6 GHz frequency range. The basic unit comprises hexagonal patches, ensuring a full 360° phase cycle. This distinctive design enables the realization of quantized phases, enhancing the overall efficiency of the MS. Using topological optimization methods for unit organization, we show 3-bit resolutions. The OAM MS proposed in this study consists of 16 ×16-unit cells. Simulation findings demonstrate how well the MS generates a first-order OAM beam. The potential applications of this proposed MS design extend to wireless communication systems. By enabling controlled OAM generation at 5.6 GHz, this innovation holds promise for advancing communication technologies, contributing to the evolution of wireless systems.
