Tesla's system clearly shows that both ends of the system are grounded - thus this section is irrelevant and should be merged with single-wire Earth return. —Preceding unsigned comment added by 74.83.50.89 (talk) 22:17, 14 May 2011 (UTC)[reply]

Two fundamentally different concepts[edit]

This page relates to:

Single wire earth return systems and
Single wire line, which is a type of waveguide (with no earth-return).

Suggest either;

Make this clear int the introduction and in the structure of the page, or
Split into two pages, or
Just make this page about single-wire waveguides, since there is already a SWER page

I agree with the need for separating the two topics. I've added some preliminary information about E-Line Does it make sense to move the guided wave entries to Surface Wave? N6gn 06:43, 21 January 2007 (UTC)[reply]

I've removed the SWER stuff. It was already duplicated in the SWER entry. But single-wire Tesla concepts have no entry of their own, so let them reside here. --Wjbeaty 10:20, 21 April 2007 (UTC)[reply]

This stuff is not verifiable. You _must_ report fact because this is an encyclopaedia. Patents protect intellectual property, but not valid scientific content. Hocus pocus pseudo science. —Preceding unsigned comment added by 146.141.15.34 (talk) 11:47, 15 May 2008 (UTC)[reply]

This stuff is verifiable. E-Line is a TM wave along a central conductor and has been previously described^[1]. Contrary to the description for Coaxial_cable which claims coax is TEM-only, a TM mode also exists there. On a single conductor, Goubau missed it completely with his premise for G-Line. The fact that an encyclopedia entry conflicts with incorrect common knowledge does not make it "hocus pocus" or "pseudo science". The E-Line entry should probably have it's own section. See an upcoming issue of Microwaves & RF magazine for more detail.N6gn (talk) 04:55, 16 February 2009 (UTC)[reply]

The issue with the E-Line section is that all of the references are from a single author, and so while this may be verifiable scientifically, it is not sufficiently widely accepted to be presented as though it were established in the field. At most, this merits a single sentence describing the general notion and linking to a patent as a reference. Ironphoenix (talk) 21:37, 6 January 2023 (UTC)[reply]

I agree, this is something close to promotion. I have drastically pruned the section, especially the uncited stuff. Until independent, peer reviewed sources start looking at this, it is hard to justify inclusion at all. SpinningSpark 10:02, 7 January 2023 (UTC)[reply]

Patents[edit]

I'd like to add,

U.S. patent 787,412, " Art of Transmitting Electrical Energy Through The Natural Mediums" Nikola Tesla

if that's okay. -- GaryPeterson (talk) 22:21, 20 November 2010 (UTC)[reply]

Parasitic return?[edit]

It should be discussed whether or not a return connection to earth (or another conductor) exists through parasitic capacitance. This may be a significant effect with high frequencies and/or with high impedance signal transmissions. (Also parasitic inductance with low impedance signals) OlavN (talk) 09:09, 28 October 2012 (UTC)[reply]
