Accurate asymptotic solution for the surface field due to apertures in a conducting cylinder
Abstract
A formula has been developed to calculate the waveguide selfadmittance of an array of aperture antennas inside a conducting cylinder. Results computed from the formula were found to be very accurate, except for the susceptance of a circumferentially polarized aperture, where the error was larger than expected, but still low enough to be acceptable in most practical cases. The geometry of the waveguide selfadmittance analysis is shown in a diagram.
