Abstract
A surface wave antenna system is presented. The surface wave antenna system is configured to be coupled to a surface and includes an antenna and a radiation modifier. The radiation modifier includes a material having a graded dielectric constant. A final portion of the radiation modifier includes material having a dielectric constant that produces a signal phase velocity in signals emitted from the radiation modifier that is substantially equal to a phase velocity of signals on the surface.
