Abstract :
We demonstrate the use of a metamaterial to transition between a guided surface mode and a designed radiative aperture distribution. Plots of the field distribution at incremental distances removed from the aperture plane illustrate the transformation from the reference mode to the designed radiative aperture field - in this case a localized plane-wave mode which produces a pencil beam at one angle.
