Claim:
1. A downhole energy transmission system, comprising: a casing string comprising a plurality of casing pipe disposed within a wellbore, wherein the casing string has at least one wall forming a cavity; a first remote electrical device disposed within the cavity of the casing string at a first location; a first stripline cable disposed toward an outer surface of the casing string within the wellbore, wherein the first stripline cable transmits a first electromagnetic directional traveling wave in a first direction along the first stripline cable; and a second stripline cable disposed adjacent to the first stripline cable at the first location, wherein the second stripline cable is electrically coupled to the first remote electrical device, wherein the first electromagnetic directional traveling wave transmitted through the first stripline cable passively reciprocates a second electromagnetic directional traveling wave in the second stripline cable, wherein the second electromagnetic directional traveling wave is used to operate the first remote electrical device, wherein the first stripline cable comprises a rugged outer surface that withstands scraping against the wellbore as the casing string is inserted into the wellbore, wherein the second electromagnetic directional traveling wave is generated without resonance, without inductive materials, and without direct physical coupling between the first stripline cable and the second stripline cable, and wherein the first electromagnetic directional traveling wave comprises an operating frequency of at least one Hertz.
