Convergence of Gaussian-beam Modes in Corrugated Conical Horns.

Abstract
Gaussian beam-mode expansion with only the fundamental
mode does not work properly when the angular region of interest is
wide. It is necessary to use higher-order mode for the expansion. A
study of the convergence of these higher order modes is presented for
the case of a corrugated conical horn. Conclusions about the number of
modes necessary for good accuracy are given.
