GTD analysis of the radiation patterns of open-ended circular cylindrical waveguide horns
TLDR
In this article, the principal plane radiation patterns of open-ended circular cylindrical waveguide horns excited in the TE_{11} mode were analyzed based on the theory of Kouyoumjian et al. and the slope diffraction formulation.Abstract:
GTD analysis of the principal plane radiation patterns of open-ended circular cylindrical waveguide horns excited in the TE_{11} mode is presented, based on the theory of Kouyoumjian et al [5]- [7] and the slope diffraction formulation [2] The study enables one to predict accurately the E - and H -plane patterns over the neat and far sidelobes and backlobes of the horn, and a good agreement is noticed between the calculated and measured radiation patterns obtained with an experimental circular waveguide horn excited in the dominant moderead more

Front-to-back ratio of a smooth metallic-wall conical horn
TL;DR: By expressing the front fields of the subject conical horn in terms of its gain, and by explicit evaluation of the known GTD expressions for its back field, a concise formula for its front-to-back (F/B) ratio is obtained.

TL;DR: In this article, a compact dyadic diffraction coefficient for electromagnetic waves obliquely incident on a curved edse formed by perfectly conducting curved plane surfaces is obtained, which is based on Keller's method of the canonical problem, which in this case is the perfectly conducting wedge illuminated by cylindrical, conical, and spherical waves.

A method for computing E -plane patterns of horn antennas
P. Russo,R. Rudduck,Leon Peters +2 more
TL;DR: In this paper, a method for calculating the total antenna pattern in the E plane, including the backlobe region, of a horn by applying diffraction theory was introduced. But the diffraction concepts developed by Sommerfeld and Pauli, which treated plane wave diffraction by a wedge, are extended so that diffraction of cylindrical waves by thin or thick edges may be treated.
