Abstract: A simulation of the OTA (Over The Air) characteristics of the proposed surface wave propagation system is verified in this paper. The system is designed on a reconfigurable porous surface where cavities are evenly distributed and can be filled with metal posts on demand. To guide the wave to the desired positions, a transmission channel employing two rows of metallic posts is created. While at the desirable position, a specially designed surface wave launcher can launch the wave into free space from the surface to the users. As shown in the simulated results, the attenuation of waves propagating on the surface is much lower than that in the free space, the proposed system can be utilized as a position-flexible radiator as described in fluid antenna systems (FAS). The simulated OTA performance of the system shows excellent characteristics of low propagation loss and high propagation efficiency, making it a good candidate for sixth generation (6G) mobile communications.
