1. An apparatus comprising:
a surface waveguide configured to support propagation of a plurality 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 plurality of electro-magnetic waves, while maintaining an insertion loss of the surface waveguide below a first threshold;
a first mode converter configured to couple first electro-magnetic waves of a first mode to the two-dimensional conductive surface, wherein second electro-magnetic waves of a second mode propagate across the two-dimensional conductive surface of the surface waveguide as a result of the coupling of the first electro-magnetic waves;
wherein a height of a field extent of the second electro-magnetic waves is maintained below a second threshold, wherein the height of the field extent of the plurality of electro-magnetic waves comprises a height at which at least a certain amount of energy is below a height above the two-dimensional conductive surface of the surface waveguide; and
wherein at least a portion of the second electro-magnetic waves propagating across the two-dimensional conductive surface are coupled to an electronic device through a second mode converter of the electronic device.
