Abstract:

The system considered is the simplest model of a nonuniform, retarding structure which permits the picture of wave propagation to be described sufficiently graphically. Moreover, it is of known interest from the viewpoint of certain applications. Thus, for example, the use in plane antennas of surface waves of retarding systems with a surface impedance varying as 1r, affords the possibility not only of obtaining the required dimensions of the effective antenna aperture but also of making a computation of the antenna just as in the computation of horn emitters.
