Propagation of Electromagnetic Waves Along Cylindrical Metasurface Structure

This paper explores the design of cylindrical leaky-wave metasurface antennas, addressing the need for antennas that conform to curved cylindrical surfaces. We introduce analytical tools for efficiently extracting the properties of electromagnetic waves propagating along cylindrical metasurfaces, enabling the suppression of curvature effects in the antenna design. A comprehensive design procedure is presented, along with a detailed design example and its corresponding simulation results. Our approach provides a fast and efficient method for designing cylindrical leaky-wave metasurface antennas, enabling the ability to radiate in the desired direction.
