A moment method analysis of a folded E-plane short in rectangular waveguide

A folded E-plane waveguide short is analyzed using a moment method formulation. A comparison of the numerical convergence of the method is shown for two different sets of basis functions: trigonometric aperture waveguide modes and weighted Gegenbauer polynomials. The theory is verified by measurements of a folded short in half-height X-band rectangular waveguide.<
