✦ Synopsis

The two-dimensional problem of launching a surface wave on a unidireetionally conducting screen by means of a parallel plate waveguide is solved by the Wiener-Hopi technique. The unidirectionally conducting screen is placed symmetrically inside the parMlel plate waveguide and continues to infinity after the waveguide terminates. A suitable mode is assumed to be incident inside the waveguide region. Expressions are derived for the efficiency of surface wave launching and for the far field. It is shown that, for a suitable choice of the physical parameters, a high launching efficiency is obtained over a wide frequency band. § 1. Introduction
