Analysis of waveguide post configurations. I  Gap immittance matrices. II  Dualgap cases
Abstract
The reaction concept in electromagnetics is used to analyze two useful kinds of postmounting structure in rectangular waveguide. The first is the general multiplepost arrangement with a gap in each post, the second being a single post with multiple gaps. The analysis derives equations for calculating the elements of the gap immittance matrices for these two structures. The analysis given in Part I is applied to two particular structures of general interest. The first is the twopost case, each post having one gap, and the second is the singlepost with two gaps. The impedance or admittance matrix elements are used to construct the gap port networks which are then used to obtain the waveguide obstacle representations. These latter representations are used to obtain experimental confirmation of the analysis.
