摘要： Apparatuses, methods, and systems for a surface wave based wireless connection to an electronic device are disclosed. One apparatus includes a surface wave guide that supports propagation of electro-magnetic waves over a two-dimensional conductive surface of the surface waveguide, wherein the two-dimensional conductive surface is treated to increase a surface reactance of the two-dimensional conductive surface over a frequency range of the electro-magnetic waves, while maintaining an insertion loss of the surface waveguide below a threshold. A first mode converter operates to couple electro-magnetic waves of a first mode to the two-dimensional conductive surface having a second mode, wherein the electro-magnetic waves of the second mode propagate across the two-dimensional conductive surface of the surface waveguide. At least a portion of the electro-magnetic waves of the two-dimensional conductive surface is coupled to an electronic device through a second mode converter of the electronic device.
