Design and Characterization of Line-Waves Waveguides

In this contribution, we outline a workflow for the design of complementary metasurfaces supporting the propagation of line-waves and check its effectiveness through both numerical and experimental results. Specifically, a semi-analytical procedure for designing the complementary patterned sheets composing line-wave waveguides is discussed and some numerical results are provided for validation purposes. Finally, it is reported the experimental results carried out on a manufactured prototype confirming the expected low-loss behavior at high-frequency.
