Description
An approximate formula is proposed for an equivalent susceptance of a circular iris in a parallel plate waveguide when a TEM mode cylindrical wave is incident from the center of the iris. Schwinger's variational method for a linear iris is generalized to the cylindrical case, and an approximate closed form formula is obtained which recovers the result of the linear iris when the circular iris is sufficiently larger than the wavelength.For a verification of the formula, an exact integral equation is formulated and solved numerically by Galerkin's method. A comparison between them shows good agreements.
