Abstract
his paper presents a new dual and complementaryimpedance metasurface platform for studying Line Waves (LWs), electromagnetic modes at interfaces of different metasurfaces like
capacitive and inductive types. The excited states, characterized by efficient one-dimensional propagation and tight interface confinement, hold promise for robust waveguide applications, especially within fifth-generation (5G) technology. The research shows that LW, supporting broadband frequencies, can be tuned through capacitive or inductive properties, with a semi-analytical model developed for in-depth analysis. Additionally, a parallel plate waveguide composed of four metasurfaces demonstrates LW robust transmission capabilities, even under longitudinal warping. This highlights their potential in wearable wireless communications and flexible electronics, showcasing their adaptability and efficiency.
