Abstract :
A novel waveguide structure is studied using a theoretical model and simulation. An impedance surface is surrounded by two lower impedance surfaces in a plane. Waves are guided losslessly within the higher impedance region. A theoretical model is proposed which predicts the dispersion relation using a ray optics method. The dispersion is predicted for each of the modes of the structure. Simulation shows similar results to the theoretical model for the lowest five modes of the structure. These results hold for a wide variety of impedance ratios and guide sizes.
