How can we make electromagnetic wave

Wyn.junior, The present redirection of "Electromagnetic wave" to "Electromagnetic radiation" seems problematic to me as well. Non-radiating electromagnetic waves exist, the Lecher wave or Sommerfeld’s single wire wave for example. According to Goubau,

"There exists an analogous connection between surface waves and space waves, like that between guided waves and “supplementary fields” simultaneously excited. The supplementary field preserves the continuity of the total field in the vicinity of the excitation source and depends on its structure and condition. In the case of a closed waveguide (concentric conductors, pipe wave guide) it is a purely reactive [non-radiating] field, while in the case of an open waveguide it is a radiating field. Whether the guided wave field or the supplementary field predominates depends entirely upon the manner of excitation and the sort of observation.

Perhaps "Electromagnetic wave" deserves an article of its own? -- GPeterson (talk) 23:44, 28 November 2015 (UTC)[reply]
