[IEEE 2020 International Workshop on Antenna Technology (iWAT) - Bucharest, Romania (2020.2.25-2020.2.28)] 2020 International Workshop on Antenna Technology (iWAT) - Numerical Analysis of Dielectric Post-Wall Waveguides

摘要： Functional post-wall waveguides that are formed by periodically distributed dielectric posts are numerically analyzed. The propagation constant and attenuation constant of the dielectric post-wall waveguide is rigorously calculated using our originally developed numerical method. The developed formulation is accurate and numerically very fast. Structural parameters of the dielectric post-wall waveguide are properly chosen in order to achieve the confinement of the field in the guiding region as strong as possible even in case of one-layered dielectric structure. The final goal of our investigations is to realize the functional dielectric post-wall waveguide-based filters, which are expected to have a practical application in THz region, where the metallic (PEC) rods are losing their properties.
