Successive SIW (Substrate Integrated Waveguides) types for width reductions by physical reasoning and formulas by analytical (use of) MoM

摘要

In this paper, the SIW studied are: beginning from a RWG (regular waveguide of solid walls), to SIW (with sidewalls of vias), then ridged and folded SIWs; for successive narrower waveguide widths. Based on physical reasoning, the analytical formulas deriv
