Abstract

The radiation of plane harmonic scalar waves from a wide-beam scalar feed horn is treated by using the mode matching method in conjunction with the Wiener-Hopf technique. The solution is exact but formal, since infinite series of unknowns and some branch-cut integrals with unknown integrands are involved. Approximation procedures based on rigorous asymptotics are used and the approximate solution to the Wiener-Hopf equations are derived in terms of infinite series of unknowns, which are determined from infinite systems of linear algebraic equations. Numerical solution of these systems is obtained for various values of the parameters of the problem, and their effects on the directivity of the circular feed horn is presented.
