<p>A broadcast communications system, comprising: a surface wave channel for guiding electromagnetic surface waves; a transmitter, coupled to said surface wave channel fortransmitting signals along said surface wave channel; one or more disrupters, arranged to be positioned at arbitrary locations along said surface wave channel, and arranged to convert said surface wave signals to space wave signals; and one or more receiver terminals, arranged to be positioned at locations corresponding to said disrupters, each terminal comprising an antenna for receiving said space wave signals. Aspects of the invention include: the one of more disrupters is a reflector arranged to be positioned on or adjacent the surface wave channel; the one of more disrupters is a surface wave to space wave converter, the converter comprising: a surface wave collector and an antenna, the surface wave launcher coupled to said antenna. Embodiments include a surface wave to space wave converter, comprising a surface wave collector; and an antenna; wherein the surface wave collector is coupled to the antenna; the surface wave collector is arranged to collect surface wave signals from a surface wave channel, and the antenna is arranged to radiate said signal as a space wave.</p> |
