Claim:
1. A transmission medium, comprising: a plurality of cables bundled together in the transmission medium, each cable comprising a core, wherein a structure of each core in the plurality of cables varies in shape to reduce cross-talk between the plurality of cables; and a dielectric layer surrounding at least a portion of each core of the plurality of cables, wherein each core is configured to enable an electromagnetic wave having a non-optical frequency range to be bound to the core rather than the dielectric layer without requiring an electrical return path, and wherein the dielectric layer reduces exposure of the electromagnetic wave to an adverse environment, wherein the core of each cable comprises a conductor having an insulation layer disposed between the conductor and the dielectric layer, wherein the insulation layer has a first dielectric constant, wherein the dielectric layer has a second dielectric constant, and wherein the first dielectric constant exceeds the second dielectric constant.
