DESIGN AND OPERATION OF A RADIATING LENS FED BY A GOUBAU BEAM-WAVEGUIDE.
Abstract
The Goubau electromagnetic beam waveguide has given rise to the interesting problem of coupling energy between the guiding system and free space in an efficient manner. In this report, a coupler consisting of dielectric lenses is considered. The Goubau electromagnetic beam waveguide is used as a feed line. The coupler modifies the field distribution so as to illuminate a large radiating lens. The method of approach to the design of such a coupler is that of geometrical optics. This approach is justified as a first approximation since the dimensions of the elements in the guiding section as well as those in the coupling system are very large compared to a wavelength.
