Apparatus, systems and methods to transmit power and data are provided. A particular apparatus to transmit power and data includes a transmission medium. The transmission medium includes at least one first frequency selective surface (FSS) layer, at least one second FSS layer, and a dielectric layer separating the at least one first FSS layer and the at least one second FSS layer. In a particular embodiment, the apparatus also includes a first coupler coupled to the transmission medium to send a signal along the transmission medium and a second coupler coupled to the transmission medium. The second coupler may receive signals via the transmission medium, receive power via the transmission medium to power devices coupled to the second coupler, process and send data via the transmission medium, or any combination thereof.
